The ef fect of conducted or inducedcurrents due to atmospheric dischargeseither from distant strikes, lightningbetween clouds or by the switchingoperation of heavy machines (whichcause overvoltages similar to thoseproduced by lightning strikes), can causedevastating damages on electronicequipment and electrical installations.

Atmospheric discharges produce voltagepeaks at the signal, very high but alsowith a very shor t duration. Currentsassociated with a direct lightning strikecan reach values over 100kA, thus evenits secondary effects bring currents thatare able to cause important damagesto the lines and equipment they areconnected to.

Most electrical lines are equipped withsecurity measures to avoid short-circuitsand electrical shocks to people. Almostevery electric board contains protectorssuch as automatic circuit breakers andRCCB. However they cannot avoid theconsequences of transient overvoltages,since their reaction is much slower thanthe voltage peak that appears.

A special example is that of UPS (Uninterrupted Power Supply). These elements assure the power supply of the equipmentsconnected to it even when there is a cut in the electricity supply. Most of these equipments also have a current rectifier whichenables a stable power supply within a ±15% variation. However, because they are sophisticated equipment with microprocessortechnology and very sensitive to overvoltages, they can suffer serious damages when subjected to transient overvoltages.

Surge Protective Devices complement the mentioned protections. In general they do not activate with small deformations in thesignal or network overloads. However, they respond in nanoseconds to voltage peaks and they are able to drive lightning current(main or secondary) to earth, safeguarding the connected equipment.

Overvoltagesand its damages

Transient overvoltages are very short duration increases in voltagebetween two conductors or between a conductor and the ground. Theycan be caused by atmospheric electrical discharges (lightning), byswitching or by electrical faults (contact with earth or short circuit).

Although transient overvoltages have existed since the creation of electricalnetworks, the need for protection is nowadays much greater. This is due toadvanced technology making electrical components ever smaller and more sensitiveto electromagnetic disturbances.

Electronic components (from valves to nanotechnology)

Types of overvoltages

The evolution of electronic systems and components together with an increasein their usage, has resulted in the last decade in a spectacular increase ofeconomic damages caused by overvoltages. This is primarily because the voltagepeak goes through smaller and more sensitive elements.

Damages caused byovervoltages

Consequences of overvoltages

The most typical transient overvoltages are caused by the operation ofpowerful machines. However, the most destructive are caused byatmospheric discharges.

Surge effects range from simple brief work interruptions to the total destruction of sensitive equipment.

DISTURBANCEInterruption of system operation, dataloss and corruption, unexplainablecomputer failures, etc…

DEGRADINGTransient overvoltages degrade, withoutuser notice, electronic components andcircuits, reducing equipment life andincreasing the possibility of failures.

DAMAGESSevere transient overvoltages candamage components, circuit boardsand can even burn or destroy theequipment as well as producing thestart of a fire.They mainly affect electronic, computerand telecommunications systems.

Causes of overvoltages andmechanisms of propagation

Causes of overvoltagesDepending on their nature, surges are classified in two categories:

SURGES DUE TO LIGHTNING STRIKES

Thunderstorms are very common and dangerous. It is estimated that on our planet, 2000 storms and 100 lightning strikestake place simultaneously on earth every second. This represents 4000 storms and 9 million flashes every day.

When lightning strikes, it causes a current impulse that can reach tens of thousands of amperes. This discharge producesan overvoltage in the electrical lines and can cause fires, damages to equipment and even casualties.

SWITCHING OVERVOLTAGES

These surges are generated in electrical lines, mainly due to the following two reasons:

Electrical switching of large machinery:Electrical motors are very inductive loads whose connection and disconnection can cause surges. There are other processescapable of producing surges, like the turning on/off of a welding arch and the connection and disconnection of powerelectronic devices.

Operation and fault in power supply network:In the case of short-circuit at any point in the network, the circuit breakers will respond by opening and the followingauto-reclosing, in the case of it being a temporary fault. Such faults can generate surges typical in the connection of inductiveloads.

All these effects imply the interruption in the normal working condition of computers and thus results in economic losses due todelays in productivity.

More impor tantly, these effects can carr y risks to people which must be avoided at all cost according to the Health andSafety Laws:Minimum requirements of health and security used by installation workers and work teams. R.D. 1215/97. Annex II, point 12.“Any installation or machine used for work purposes, and which could be reached by lightning, should be protected against itseffects using adequate devices and measures.”.

The prevailing mechanism of switching overvoltages is conduction, because it starts in the very power supply networks.It’s in atmospheric discharges where all kinds of different propagation methods can be observed. Therefore, we candifferentiate between the following methods:

Mechanisms of propagation

CONDUCTED OVERVOLTAGES

Lightning can strike aerial lines directly. Surges then propagate and reach the user, finally diverting to ground through theequipment, provoking failures.

A common mistake is to think that hitting discharges in power distribution lines (Medium Voltage) don’t reach those of LowVoltage because of the galvanic insulation provided by the existing transformer. However, this is not true due to the factthat the before mentioned insulation is effective for nominal frequencies in the network, while for the wave forms associatedwith lightning, the transformer produces little attenuation.

INDUCED OVERVOLTAGES

The electromagnetic field produced by electric discharges induces transient current in nearby conductors, entering then thestructures and harming the equipment.

CAPACITIVE OVERVOLTAGES

There always exists a capacitive coupling, also called stray capacity, between every pair of conductors. Overvoltages dueto capacitive coupling become more important as the voltage waveform velocity increases.

VOLTAGE RAISES AT THE GROUNDING

This mechanism is a special form of conducted overvoltages (described before) but due to its elevated incidence, it deservesa special mention.

When lightning disperses in the earth, lightning current can raise the ground voltage around the impact point severalthousands of volts as a consequence of the passing current.

Any object on the affected ground will acquire the associated voltage during that time, which can produce a dangerousvoltage difference to other points on the installation. Take special attention to buried metallic objects such as piping andearth terminals.

How do overvoltages enter the equipment?

Power supply, telephone, TV or datalines often cover long distances andare connected to ver y sensitiveequipment. This condition makesthe line especially receptive toover voltages which then will betransmitted by conduction to theconnected equipment.

It is convenient to pay special attentionto aerial lines that connect sensitiveequipment even in protected envi-ronments as it is probable thatdangerous voltages can be induced. Itis also important to take into accountthat lightning and power switchinggenerate high magnitude electro-magnetic fields thus inducing currentsin the conductors placed inside thisfield. Even lightning strikes from cloudto cloud can cause damages inelectrical installations.

In general, it is convenient to install surge protection at any line enteringor leaving a building that connects or could connect in the future sensitiveequipment.

Finally, lightning ef fects can enterthrough the earthing network, changingthe reference of voltage of all theequipment connected to it or to theelectrical power supply line itself. Themost susceptible equipments in thiscase are those that have the voltagesof its elements referenced to twodifferent grounds.

In this case, it is recommended to linkall the grounds, including those of thelightning protection system in order toavoid overvoltages and larger flowingcurrents.

In addition, when there are severalbuildings in the same complex, the riskwi l l usual ly increase due tocrossconnections.

In order to design anaccurate SurgeProtection System, youwill first need to knowthe overvoltage risk inthe area (L) and theprobability of anequipment to bereached by a surgethrough the line (E).

The calculation of thesetwo risk index (L and E)are based on theguidelines: ITC-BT-23 ofRBT2002 and on theUNE 21186:1996standard.

The aim of a surge protection system is to assure the continuity of electrical power supply and minimise to anacceptable level for people and equipment any possible damages due to incoming transient surges.The most important feature of surge arresters is its rapid response time.

Surge protectionsystem design guide

Transient overvoltages could easily reach several kilovolts in a few microseconds. During this raise time, while the protectorhas not reacted, this increasing voltage reaches the connected equipment. Generally, the response time of the arrestersvaries between 20 and 100 nanoseconds.

Surge arresters can be installed in series or parallel, but in all cases they must remain inactive under normal conditions.Once the overvoltage starts, the protector will start working, leading the lightning current to ground. Momentary interruptionsshould not be made, that is to say, the final user should not notice the SPD action.

Sustained interruptions are not allowed: when the overvoltage has been absorbed, the protector should return to its inactivestate without affecting the normal working of the line. In those cases where the components of the protector have suffereda bigger overvoltage than they can withstand, the failure mode will be open circuit thus avoiding the short-circuit of the line.Most of protectors are provided with a visual or remote warning which activates when the protector should be replaced.

No protector nowadays is able to both absorb high currents and leave harmless residual voltage pass through. Thereforea set of devices are required in order to achieve a good balance between current and voltage, minimising any further damageson the equipment. From the users point of view, this is the most important fact, the residual voltage should not representa threat.

APLICACIONES TECNOLOGICAS, S.A. has tested all its SPDs in officialand independent laboratories successfully achieving all values describedin their technical sheets and labels.

Regulations

The regulations of series 61643 of the International Electrotechnical Committee (IEC) define the requirements andimplementation of surge protectors. Some of these regulations have already been adopted as European standards (EN).

There are other related regulations, the most important one being the Lightning Protection Systems Regulation includingits electromagnetical effects. Regulations for the installation of electrical boards should always be fulfilled.

The tests carried out on the SPDs are principally based on regulation IEC 61643, although APLICACIONES TECNOLOGICASproducts also comply with the requirements of UL1449.

Let’s say that UL 1449 is a security regulation. It is not a regulation on the working condition of the SPD, it does not testthe current and voltage values stated on the protector, however, it does test its safety.

On the other hand, IEC 61643 certifies both security and working conditions.

Tests carried out. Series IEC 61643According to this regulation, SPDs can be classified into three classes depending on what they are used for. 1) If they aresupposed to withstand direct lightning strikes, 2) secondary effects or 3) attenuated overvoltages. According to the classestablished, the manufacturer provides a piece of information which characterises the device and determines the type oftest to be carried out.

Although there is no settled value defined by the regulations for each class, any stated value on the label and on its technicaldatasheet must be tested and proved on laboratories according regulations.

Standard impulse current tests

There are two dif ferent current tests that simulate theeffects of a lightning strike:

• Direct lightning strike test, modelled on wave form10/350µs in order to determine Iimp.

• Secondary lightning effects test and switching elements,with wave 8/20µs in order to determine Imax. Due to thedifferent make up of the wave form tested, the tests withIimp have a much higher energy than the tests with Imax

and In.

Impulse current wavesapplied to the

protectors againstovervoltages in order

to check itscharacteristics. The

area of each curve inthis graph shows the

specific energy applied.

During the tests, the SPDs are submitted to repeated current and voltage impulses, measuring the residual voltage. Theestablished Level of Protection (Up) cannot be surpassed in any test. Residual voltage does not always increase with thecurrent value: some critical values may exist for currents lower than the maximal. Therefore it is very important to applystepped current impulses, over and below the nominal current, in order to assure the highest voltage the protector may letthrough. Thermic and mechanical tests are also performed.

Other applicable standards

There are other regulations to take into account when designing and installing SPDs. On the one hand, these protectorsare part of the internal protection described in the following lightning protection standard:

Standard Norm UNE 21186 and NFC 17102, “Protection of structures and of open areas against lightning usingearly streamer emission air terminals”.

Standard UNE 21185, BS 6651, NFC 61-0740 and IEC61024 (and its substitute series IEC62305),“Protection of structures against lightning and general principles using conventional systems (meshed conductors and franklinrods)”.

Standard IEC61312 (and its substitute series IEC62305), “Protection of structures against electromagneticeffects of lightning.”

Electrical codesSPDs should meet every specific regulation of the lines where they are installed. In the case of power supply lines, SPDsshould comply with each country’s electrotechnical regulation (for example in Great Britain BS 7671 "Requirements forelectrical installations" and in Spain RBT2002 "Low Voltage Electrotechnical Regulation"; this last regulation makes a specialreference to overvoltage protection in instruction ITC-BT-23).

SPD selection

The most important parameters to take into account are:

a. Where the area to be protected is located.b. Maximum residual voltage allowed.c. Additional parameters of the line.

To protect any equipmentcorrectly, it is necessary to

know in detail all itscharacteristics.

a.- Zone of protection

Lightning protection standards, as IEC61312, define Lightning Protection Zones (LPZ) depending on the electromagneticcharacteristics of each area around and inside the structure to be protected. For each of these zones, the damage thatsurges can cause is different, and therefore equipment should be protected according to this risk.

A good coordination between them is very important: they should act in coordinatedstages and be able to withstand lightning currents letting residual voltages thatare harmless to the equipment.

Regulations describe three different types of SPD according to the area where they are located:

Surge Protective Devices areinstalled in the transitions

between zones.

Class I Protectors:

Class I SPDs should be tested with10/350µs lightning impulse wave,simulating the effects of direct lightningdischarges.To be installed where lightning currentsand electromagnetic ef fects areunattenuated.

Class II Protectors:

Class II SPDs should be tested with8/20µs cur rent impulse wave,simulating lightning secondary effects.To be installed where lightning currentsand electromagnetic effects are alreadyattenuated.

Class III Protectors:

Class III SPDs should be tested withcombination impulse wave but with lowvalues, simulating very attenuatedover voltages. Normally they areinstalled near the equipment and havelow residual voltages.

One method of reducing electromagnetic fields is the shielding of structures, rooms and/or equipment. In case of buildings,the equipotential bonding of metallic objects achieves disturbance reductions. If this interconnection is carried out duringthe construction of the building, then later protection is more effective and less costly.

In any case, all the lines entering or leaving a zone should be protected with the proper device in order to avoid surges.

An important feature of SPDs isits residual voltage. If it is low,the protected equipment will sufferless damage when surges reachhigh levels, even if they arecapable of supporting them.

b.- Permitted Residual Voltage

However, there are more robust equipments or with internal protections whichdon’t need especially low residual voltage, whilst other equipments can be verysensitive hence demanding very low residual voltage. SPDs in this last case mustbe installed near the equipment. In order to select an adequate protector, thecharacteristics of each connected equipment should be taken into account.

ELPS

Example of power supply overvoltage protectiontaking into account the connected equipment

It is imperative that the protectordoesn’t affect the working condition

of the line and doesn’t producesignificant losses of signal.

c.- Additional parameters of the line

To finalise the details of the protection, it is convenient and in some cases, essential to know the characteristics of theline to be protected, such as the following:

•Maximum working voltage, to make sure the SPD activates at an acceptable voltage level to the user.

•Type of voltage: alternate, continuous, impulse, etc.•Working current of the line, absolutely essential if an element is inserted in

series.•Supply system TN, TT, IT (in power supply lines) to protect the adequate lines.•Characteristics of the connections.

SPD SELECTION

1.- Note the line characteristics in order to find out maximum voltage in continuous and/or alternate in each conductor.Select the SPDs providing:

Uc > maximum working voltage of the line

2.- Select the SPD type and itsmaximum current depending on theeffects it should withstand:

3.- Select the SPD residual voltageaccording to the equipment to beprotected. For example, for powersupply lines it is recommended:

SPD Coordination

Once the requirements of the protection have been defined, it will probably be the case that one commercial device doesnot meet the demanded requirements of discharge intensity and residual voltage. For this reason, the installation andcoordination of several devices is needed.

In general, the higher the current withstanding capacity the higher the residual voltage and therefore its level of protection.

Therefore, a proper protection requires coordinated SPDs, with several protection stages acting sequentially and being able,on one side, of withstanding all the lightning current and, on another side, of letting a residual voltage harmless for theexisting or future installed equipment.

If SPDs are connected to the same electric point, without any impedance separating them, then the fastest one will withstandthe whole surge while the toughest SPD has no time to activate, If the overvoltage is very large, the SPD could be destroyedor damaged. Even if the surge would not harm the SPD, there is no sense in installing a robust protector, with a huge currentwithstanding capability, if it never acts.

Aplicaciones Tecnológicas, S.A. supplies complete cabinets where allstages are already installed and coordinated by a decoupling inductor,suitable for those installations where separation by cable is not achievable.

For two SPDs to be correctly coordinated,the length of the cable between themshould be at least 10 metres. If this isnot possible (for example, if both werein the same electric board), a decouplinginductor should be installed betweenthem.

Usually, the first protection is aspark gap.

Protection stages

Spark gaps typically remain completely open, with no flowing current, while signalis normal. Each one has its characteristic breakdown voltage (although it variesslightly with the wave form). When this voltage is surpassed, then the componentbecomes short-circuited, driving all the current to ground. When the high level

voltage disappears, these componentsreturn to inactive status, that is, to bean open circuit.

The element forming the secondprotection, tighter than the first one,is usually a varistor. Varistors arevariable resistances. Their impedanceis very high when voltage is normal,and it lowers in a non-linear way whenvoltage increases. In general, they arefaster than gas discharge tubes buttheir disadvantage is that, while voltageis normal, their impedance is very highbut still produces current leakage.

The third protection barrier is normallyTransient Voltage Suppressor Diodes,very fast elements, capable of lettingvery low residual voltages but unableto withstand currents over severalamperes.

Aplicaciones Tecnológicas, S.A. Surge Protective Devices have beentested not only individually but also in coordination with other protectorsof different stages.

Many SPDs are formed by the combination of these elements or by several of themcoordinated in a single device. Decoupling elements are normally resistances orinductors with very low impedances because, being in series with the line, the currentflows through them continuously. If impedances were high, they would cause unnecessarylosses and consumptions.

Normally the problem of electrical consumptions is worse in power supply lines, whereflowing current is of amperes. For data lines, the current flowing is of miliamperes,hence the consumption is not important. However, the working voltages of electroniccomponents are usually very low thus a significative voltage drop at the decouplingimpedance must be avoided, since it could cause disturbances in data transmissions.ATBARRIER (page 72):

For power supply lines, dif ferentcombinations of ATSHOCK, ATSUB andATCOVER have been tested, using ATLINKdevices as decoupling inductors, verifyingtheir coordination and proper workingeven with lightning impulse waves (100kA,10/350µs).

supply lines

Power supply lines enter the structures from outdoor and distribute the current to all the electrical and electronicalequipment, ranging from robust motors to most sensitive devices. Mains power supply often suffer small oscillations,harmonics, sudden increases and even severer disturbances such as short-circuits or derivations to ground. Devicesfor solving these kind of problems and safeguarding the equipment are available in the market (circuit breakers, residualcurrent circuit breakers, fuses, etc), however the response time of these devices is too slow and do not react properlyagainst transient overvoltages.

Surge Protective Devices for power supply lines complement the above mentioned devices, since they only protectagainst transient overvoltages caused by lightning discharges and power switching. In general, they are to be installedin parallel with the line in order to avoid unnecessary losses and consumptions although some elements, such asdecoupling inductors must be installed in series. When a SPD has any element in series with the line then its maximumcontinuous working current must be clearly specified, indicating the maximum current that can flow through it continuously.Nonetheless, the impedance should always be very low.

Protection of power supply lines

Within power supply surge suppression, Aplicaciones Tecnológicas, S.A.supplies several SPD series depending on the intensity of the expecteddischarge current in the area to be protected andon the sensitivity of the protected equipment.

When different protection stages areused, it is essential that SPDs arewell coordinated when a surge occurs.Surge protection series for powersupply lines are the following:

ATSHOCK seriesCan withstand direct lightning strikes (100kA, 10/350µs).

ATSHIELD seriesThey combine very robust elements with clampling components in order to achieve a large absorption capacity of the directlightning strike together with a low residual voltage.

ATSUB seriesCan withstand tens of kiloamperes and reduce the overvoltage significantly to levels that are not harmful to the equipment.

ATCOVER seriesRobust and very complete, protects all phases quickly and efficiently, leaving a low residual voltage.

ATSOUND seriesAcoustic signalling module, complementing the remote warning of ATSUB and ATCOVER series.

ATLINK seriesFor the coordination of protection stages.

ATCOMPACT seriesCabinet for multipolar protection made up of single-polar elements.

ATBARRIER seriesProtected coordinated cabinet.

EARTH

Each ATSHOCK Lprotects onephase

Can withstand direct lightning currents (modelized under 100kA, waveshape10/350µs), leaving a residual voltage of a few kilovolts. They consist of encapsulatedspark gaps, thus no plasma arcs are produced outside the casing. They areinstalled in points likely to directly receive large lightning discharges. They shouldalways be used in coordination with ATSUB and/or ATCOVER SPD series as theirresidual voltage all alone is still harmful to the connected equipment. They aresingle-pole protectors (protect only one phase or the neutral depending on theearth) and can be installed in all types of supply systems.

ATSHIELD Series

Protectors which bring together both, the quick response time of the zinc-oxidevaristors together with the shunt capacity of spark gaps. They are designed andtested as a Class I protector, meaning that they can withstand tens of kiloamperesof direct atmospheric discharge intensity (wave 10/350µs), leaving a non harmfulamount of residual voltage to the connected equipment. They are single-poleprotectors (protect only one phase or neutral depending on the earth) and can beinstalled in all types of supply systems. They have a bright warning light to detectany possible failure in its proper working.

EARTH

Made up of zinc oxide varistors and have a visual alarm when the SPD is out ofservice. They are single-pole SPDs (they protect one phase or neutral) and canbe installed in all types of supply systems.

ATSUB protectors can withstand tens of kiloamperes for a 8/20µs (waveformsimulating lightning secondary effects) and they reduce surges to harmless levelsfor the protected equipment.

These characteristics, together with its small size and low cost, make them themost suitable SPDs for installation in secondary boards and close to the equipment. They can be combined with other ATSUB,ATSHOCK (which would receive the main lightning current) and with ATCOVER protectors, which leave a lower residual voltage.In any case, there must be 10 metres of cable or ATLINK devices for a proper coordination between protection stages.

There are also versions with pluggable modules (ATSUB-P) for a quick substitution in case of repeated overvoltages andversions with remote warning (ATSUB-PR).

ATCOVER Series

ATCOVER SPD series combine in a single device, protection in common mode (toearth) and differential mode (between lines). They can withstand currents up to30kA 8/20µs, leaving very low residual voltages, completely harmless to theconnected equipment. They have an internal combination of varistors and gasdischarge tubes that avoid current leakage while the line is working under normalconditions.

They are provided with a visual alarm and floating changeover contact output forremote control thus allowing the monitoring of its proper working. They should beinstalled at supply distribution systems with neutral. Three phase and single-phaseversions are available for different network voltages. They can be installed incombination with other SPDs from ATSHOCK and ATSUB Series, always linked byat least 10 meters of cable or decoupling inductor as ATLINK.

Power supply networks are built following different wiring systems, defined in LowVoltage codes. It is necessary to know this data of the line to be protected inorder to determine the surge protection installation.

Systems are named using a letter code indicating the situation of the supply withrespect to the earthing (T indicates direct connection, I means isolation, Nconnection to neutral). The main supply systems are the following:

Power supply systemsSupply systems are characterizedby their connections, on one side,with the distribution or supplygrounding network and, on theother side, the receiver installationground.

TN system

TN systems have one point of the supply, generally the neutral, directly connectedto earth. The exposed-conductive-part of receiver’s installations is connected tothat point by protective conductors.

There are several TN distribution systems depending on the relative arrangementof the neutral conductor and the protective earth (PE) conductor.

When the protective earth (PE) and the neutral are combined in the same conductoralong the whole system (TN-C systems) then surge protection is complete just byinstalling SPDs between each phase and the mentioned common neutral/earthconductor. However, if neutral and earth are two different conductors (TN-Ssystems), then SPDs should also be installed between neutral and ear th.

TT system

TT Systems have one point of the supply, generally the neutral, directly connectedto earth. The exposed-conductive-part of receiver’s installations is connected toa separate ground.

In order to protect these systems against transient overvoltages, it is necessaryto place at least some SPDs between each phase and ground, and betweenneutral and ground. In addition, it is recommended to protect each phase and neutral. However, it is not convenient to haveonly phase-neutral plus neutral-ground protection since a surge produced at one phase would transmit to the whole installationthrough the neutral conductor.

IT system

IT Systems have no direct connection between one point of the supply and theground, but the exposed-conductive-part of receiver’s installations is directlyconnected to ground.

In this type of systems, the neutral is not recommended to be distributed. However,surge protection needs a common point where the earth terminals of the SPDsmust be connected, and this common point will be connected to earth througha SPD for neutral (ATSHOCK-N, ATSUB-N).

Notes: (1) The three ATSUB that are installed between phases and neutral at TT systems are recommendable, although the lines are also protected without them.(2) Specified fuses for each SPD should be used in cases where the same or lower protection is not provided in the upstream power supply.(3) ATLINK devices are not necessary if there are at least 10 meters cable between the protectors.(4) For an efficient protection, it is convenient that all the earthing systems of the structure are bonded together.

Other combinations• All ATSUB, including ATSUB N, can be substituted by a single ATCOVER380T• ATSHOCK can be substituted by ATSUB40 or ATSUB60, although then the withstood current will be lower.• If only the first stage protection is installed, then the residual voltage would be too high, possibly damaging the equipment.• Single protection (ATSUB or ATCOVER) can be installed if lightning currents reaching the installation are not expected to be higher

than those the SPD can withstand, and also if no transients are expected to be generated indoor.• Further protection stages may be installed, where the surge will arrive more attenuated. They should be able to reduce transient

overvoltages to very low levels (for example, ATCOVER series).

LINE

As a complement of all the range of SPD of Aplicaciones TecnológicasS.A., this acoustic module is available aiming the warning every time atransient overvoltage leaves out of order any SPD.

This is specially suggested in systems where a high degree of safety and confidenceis requested.

It works gathering wired signals from the different SPD that are meant to bemonitored and as a consequence of every failure of them, an alarm signal willbe activated by mean of warning ring tones.

They are fully compatible devices with alls SPDs provided with remote controlsignal previously mentioned (ATSUBs and ATCOVERs). Several remote controlterminals can be wired in series and inserted into the ATSOUND thus giving analarm if any SPD is harmed. The warning lights and mechanical warnings allowto determine what SPD needs to be replaced in every particular case.

A tighter protection stage has been installed in the same module in order toprevent residual dangerous overvoltages after ATSUB and ATCOVER from alteringthe proper way of working.

LINE

INSTALLATIONATLINK inductors are to be installed in series with the LV power supply line, that is, cuttingthe line and connecting the obtained cable ends to the input and output connectors of theATLINK. One ATLINK is needed for each line and another one for the neutral. There is noground connection.The power should be disconnected during the installation of the SPD.Coordinates mainly ATSHOCK with ATSUB and/or ATCOVER surge protective devices whenthey cannot be separated by a cable at least 10 meters long.

NEUTRAL

A proper protection against transient overvoltages needs a goodcoordination between SPDs. ATLINK inductors provide decoupling betweenSPDs when they are connected in parallel at a same line. Thus, each oneacts at the right moment, achieving the double objective: withstandingthe lightning current and reducing the overvoltage to an acceptable levelfor the connected equipment.

One ATLINK is needed for each line and another for neutral. For their selectionthe line working current must be taken into account, since this current will flowcontinuously through the device.

Its coordination capabiliy has been tested and certified using lightning wave10/350µs according to IEC61312-3.

• Allows the installation of SPDs of different classes in the same place, sincethe inductor substitutes the necessary length of cable for SPD coordination.

• Robust connectors, suitable for all kind of connections.

A proper surge protection is only achieved if all the stages are wellcoordinated. Otherwise the most robust protection will not act, possiblycausing the destruction of the most sensitive protectors and even theequipment that they should protect.

For the working of all the protections, they must be separated by at least 10 meterscable. If this were not possible, a decoupling inductor should be installed betweenthe protection stages. ATBARRIER boxes contain all the necessary elements for acoordinated protection.

ATBARRIER boxes are to be installed in serieswith the Low Voltage line, connected to line/s,neutral and ground. Fuses or circuit breakersmust be present upstream. They will bedisconnected during the installation for workingsecurity. If this protection does not exist, fusesmust be installed in series with the box.Their installation is recommended where directlightning currents could penetrate and verysensitive equipment is connected, withoutdistance enough for SPD coordination.

PROTECTIÓN OF A PHOTOVOLTAIC INSTALLATION WITH AND WITHOUTLIGHTNING PROTECTION SYSTEM (LPS)

As shown on the diagram above, two cases may exist:

1) With External Lightning Protection System: If distancebetween panels and inverter is bigger more than 10m, aATVOLT or an ATPV should be placed depending on theoutcoming voltage from the panel. An ATPV must be placeat the DC inverter input.

2) Without External Lightning Protection System: A robustATSHOCK SPD should be used in order to withstand directlightning strike current. An ATPV must be placed at theinverter input.

Electrical installation should be protected as follows:

- A medium ATSUB protector should be placed in the mainswitchboard.

- If generated power is used for local needs, it is recommendedto place a tight protector ATCOVER in the distribution boardin order to avoid high residual voltages.

- If generated power is to export to the electrical networkthrough an owned transformation center, a ATSHOCK shouldbe placed in order to avoid transient overvoltages in the line.

Surgeprotection for

telecommunicationlines

Surges often enter structures via telephone and data lines, thus affecting theequipment. The same as power supply lines, they can cover large distances andconnect very sensitive electronic equipment. Besides, telephone and data linesconvey normally very low currents and reach the most fragile components.Examining any electronic device, it is clear that the power supply part is formedby more robust elements, while data communication lines connect directly tointegrated circuits, other electronic components through the printed board thintracks. Surges can cause severe damages in these tracks and components,degrading or destroying them and also affecting the data they store.

Telephone lines connect not only phone terminals but also more important and sensitive equipment, such as faxes andmodems, inside and outside computers. Furthermore, one of the consequences of the global use of Internet is that manymachines (PLCs, electrical house-hold, etc.) activate through the telephone line.

Another very common trend is to design all kind of devices for remote distance controlling. This process often means themultiplication of cross-connections and wiring between devices that are placed in separated buildings or with differentgrounding. The risk of surges damaging the equipment increases then considerably, causing important economic lossesnot only due to the equipment damage but also the delay or cancellation of the processes and the services they shouldsupply. Protecting communication lines against surges can solve all these problems.

Data and telephone lines need a wideprevious study of the systems to beprotected. Telecommunications is afield in constant evolution, where highprecision is required and many differentprocedures exist. Each transmissionprotocol has its own working voltage,type of connection, pin-out, etc. Allthese data should be well known beforedesigning a surge protection strategythat, firstly, does not affect the userand, secondly, is ef ficient againsttransient overvoltages.

Due to their placement, aerials are one of the most exposed elementsto lightning discharges. Even when an external lightning protectionsystem exists, the discharge secondary effects can affect the TV or RFsignals.

ATFREQ Surge Protective Devices protect the signal cable deriving the inducedand conducted surges to the ground, thus avoiding damages to the communicationand TV equipment and to the connected devices (DVD, video, decoders, homecinema sets, etc.)

• Optimum coupling with imperceptible losses.• Small attenuation in the signal even for very high

frequencies.• Short response times.• Discharge takes place in an internal encapsulated

element, without external flashes.• Small size.• Specific connectors for each application.

Power supply protection forminor magnitude overvoltage areas

This protection is specially aimed for working in coordination with the power supplyprotection already seen in previous sections. Usually, one talks about tightprotection compared to that seen in other sections, called coarse or medium.

This is focused to protect equipments more sensitive to overvoltages (computersystems, measures, electronics, etc.) and final customer equipments.

It’s more flexible since it allows protection at both installation level (distributionboard) and working place or particular equipment.

INSTALLATIONATFILTER devices are to be installed in series with the power supply line, that is, cuttingthe line and connecting the obtained cable ends to the input and output connectors. Pleasepay attention to these connections since if terminals are wrongly wired, a short circuit mayhappen.On the other hand, it’s of capital importance a right wiring of input/output terminals. If not,protector components won’t act properly.Linking the earth terminal to ground is a must.The power should be disconnected during the installation of the SPD. The protector isready to be fitted on the DIN rail of the distribution board, the closest to the equipmentto be protected against overvoltages and screened against electromagnetic noise.

Earth connection is a must. Earthing in all the installation must be bonded either directlyor by a spark gap and resistance should be lower than 10Ω. If the indications of thisdatasheet are not fulfilled during the use or installation of the SPDs, the protection assuredby this device could be endangered.

Backup overcurrent protectionAn overcurrent device (fuse or circuitbreaker), which is a part of theelectrical installation, located up-stream the SPD to avoid overheatingand destruction if SPD is not able tointerrupt the sustained short-circuitcurrent.

Charge QEquals the time integral of thedischarge current; expressed in A·s.

Combination type SPDAn SPD that incorporates both voltageswitching type components andvoltage limiting type components.May exhibit voltage switchingbehaviour, voltage limiting behaviouror a combination of both dependingon the characteristics of the appliedvoltage.

Combination waveThe combination wave is deliveredby a generator that applies a1,2/50µs voltage impulse opencircuit, and 8/20µs current impulseshort circuit. The voltage parameters,current and waveform produced aredetermined by the generator and theimpedance of the protector.

Follow current (If)Current supplied by the electricalpower system and flowing throughthe SPD after a discharge currentimpulse; it is expressed in kARMS.

Follow (Up) current extinguishingcapabilityWhen Spark Gaps or Gas DischargeTubes ignite, there is a dielectricbreakdown, an ignition arc and theresulting short circuit between thetwo protected conductors. Whenworking voltage conditions return,the referred short circuit and the arcmust disappear. The follow up currentextinguishing capability refers to thecurrent that the SPD is capable ofextinguishing by itself in order tocome back to working isolationconditions.

Impulse current (Iimp)Maximum peak value of a 10/350µscurrent wave with a determinedcharge and energy, applied to theprotector which diverts it to groundsafely.

Level of protection (Up)Parameter that characterises theperformance of the SPD in limitingthe voltage across its terminals andthat is chosen from a chart of values.This value, in volts, should not besurpassed by any of the residualvoltage values measured during thetests, including current impulses and1,2/50µs voltage tests.

Maximum continuous operatingvoltage (Uc)Maximum DC or rms voltage that canbe continuously applied to the SPDwithout causing its activation.

Technicalglossary

Specific energy W/R for Class IThe energy dissipated by the impulsecurrent Iimp in a unit resistance.This is equal to the power integralbetween the equivalent resistanceduring the discharge. Expressed inkJ/Ω et en kA2s.

Surge Protective Device (SPD)A device intended to limit transientovervoltages and divert surgecurrents. It contains at least onenonlinear component.There are one-port SPDs which areconnected in parallel or two-port SPDswhich have specific series impedanceinserted between the terminals.They are also referred as arrestersor just protectors. In this catalogue,SPD, arresters and protectors meanthe same thing.

Surge / Transient overvoltageA surge is a transient overvoltagepropagating along a line characterizedby a rapid increase followed by aslower decrease.Transient overvoltages are everyrising in the voltage wave overnominal conditions for a given rangeof time.In this catalogue, both surge andtransient overvoltages or justovervoltages are used in the samesense, that of rapid increase andlower decrease.

Thermal stabilityAn SPD is thermally stable if afterthe operating duty test, where it isconnected to maximum continuousoperating voltage and at specifiedambient temperature conditions, thetemperature begins to decrease withtime. It is monitored during 30minutes, the active power dissipationmust show constant decline for thelast 15 minutes.

Maximum discharge current (Imax)for class test IIMaximum peak value with wave8/20µs which has been applied tothe protector, which has beendiverted in a safe way to ground.

Methods of protectionAn SPD can be connected Line toLine, Line to Ground, Line to Neutral,Neutral to Ground or a combinationof them all. These paths are referredas methods of protection.

Nominal current (IN)RMS value of the flowing current ina line under working conditions inorder to have a proper SPD working.

Nominal discharge current (In)Peak value of a 8/20µs current wavethat the SPD can withstand severaltimes.

Nominal voltage (Un)It is the DC or rms AC voltage of theline under normal conditions so thatthe SPD works correctly.

Response time (tr):Parameter that characterizes therapidity of the SPD activation. It canvary with different slopes of theapplied waveshape, although ingeneral the response time for thevaristor is considered to be 25ns,while spark gap is 100ns.

Sparkover voltage of a voltageswitching SPDMaximum voltage value beforedisruptive discharge between theelectrodes of the gap of a SPD (emptyspace between terminals).It is used for classification of theSPD class I and II by testing theimpulse with waveshape 1,2/50µs.

SPD disconnectorA device which will disconnect theSPD from the system in the event offailure. It is used to avoid a sustainedfault in the system and to give avisible indication of the protector’sfault. Some SPDs are fitted withfloating changeover contact forremote signalling.

Voltage limiting type SPDAn SPD that has a high impedancewhen no surge is present, but willcontinuously reduce it with increasedsurge current and voltage; typicalexamples of components used asnonlinear devices are varistors andsuppressor diodes.

Voltage switching type SPDAn SPD that has a high impedancewhen no surge is present, but canhave a sudden change in impedanceto a low value in response to a voltagesurge in the line it protects. Typicalexamples are spark gaps, gas tubes,thyristors and triacs.
