Surge protectors to protect electrical installations aiganst lightning and other overvoltage's

Safety of power supply

To ensure personnel and equipment safety, operating conditions of electrical installations have to be protected and monitored continuously. The physical quantities of lightning and other overvoltage's damaged electronic equipment and the electrical installations

NSG Spark Gap Diverters (Power protection Type 1) have high surge ratings suitable for point of entry protection in installations with highly exposed overhead LV power lines with no local transformer.

Power Quality and Energy Measurement

SurgeA surge, or transient disturbance, is a short temporary overvol-tage that can cause damage to electrical equipment. Surges have a very short duration with most of the energy dissipated within 1 millisecond. These over voltages can occur as a result of lightning discharges, electrical system switching or electro-static discharge. Other terms often used to describe a surge are ‘spike’, ‘transient overvoltage’, or ‘lightning impulse’.

Surge Protection DeviceSurge protection devices are designed to limit the surge exposure towards electrical and electronic equipment. The purpose of a surge protection devise is to provide an alternate, low impedance path for the surge current. This protects equip-ment from overcurrent degradation and dramatically reduces the voltage exposure.

Short Form Product GuideIntroduction

Rated Impulse VoltageThe following table provides a list of standard impulse voltage withstand levels for 230/400V based electrical equipment. The table is sourced from IEC 60664-1.The rated impulse voltage of electrical equipment is the maximum transient voltage that the equipment is designed to withstand without insulation breakdown. The table relates to insulation breakdown, namely the withstand voltage bet-ween each line and earth. The line to line breakdown voltage, resulting in component damage, is generally much lower than this; typically for 230/400V mains powered equipment it is around 700-800V. When designing a surge protection scheme for a given site, it is important that the surge protection devise selection provides a residual voltage lower than the impulse voltage rating of the equipment being protected in all modes, namely line to line and line to earth.

Overvoltage Category Rated Impulse Voltage Equipment Examples

I 1500V

Sensitive electrical plug-in equipment. Example: Televisions, Computers, PLC Equip-ment, PABX, Uninterruptable Power Supplies,

Medical Equipment, Microcontroller based appliances, etc.

II 2500V General domestic fixed appliances, portable tools, etc.

III 4000V Fixed industrial installation switchgear or high reliability and/or availability equipment

IV 6000V Electricity meters and primary fusing and primary circuit breakers

Surge Types

Direct Lightning StrikesA direct strike occurs when a structure or an electrical service conductor is hit directly by a cloud to ground lightning strike. A direct strike surge is the strongest and most destructive of surge sources. The average lightning strike represents 30,000A (30kA) of current flow up to a possible maximum of 200,000A (200kA).

Lightning Indirect EffectsA lightning strike does not have to hit equipment or cabling directly for it to cause damage. The majority of current surges are caused by the indirect effects of the lightning strike. For example, by lightning striking a building containing electrical and electronic equipment.

Earth Potential RiseAs the energy from a cloud to ground lightning strike is dis-sipated to earth, a radiating field of earth potential is created due to the resistance of the ground. Sites or equipment groun-ded near to the strike point will rise to a much higher potential than sites or equipment further away. Any power or signal cabling between these sites will be used as a current path due to the high potential difference. This is why surge protection is a requirement for cables running between equipment with discrete earthing. In the example below, even though light-ning only strikes the building on the left, surge protection is required at both buildings.

LEMP EffectsDue to the high current and voltage present during a cloud to cloud or a cloud to ground strike, a ‘Lightning Electromagnetic Pulse’ (LEMP) is released into the atmosphere. This imposes a

surge onto signal and power cabling through induction of the magnetic field and capacitive coupling of the electric field. The energy resulting from the LEMP effect is much lower than the previous sources, but still affects sensitive equipment and long signal interconnects. As before, surge protection is required at both ends of the cable, that is at each building.

Switching SurgesSwitching surges occur when reactive electrical equipment such as capacitors or inductors are switched into and out of the grid. Switching surges are by far the most prominent source of surges to which equipment may be exposed. Swit-ching surges are generally quite low in energy but can still damage sensitive equipment and cause component degrada-tion leading to operational failure.

Risk Assessment

The level of protection recommended for a site is dependent on environmental factors affecting the potential surge exposure. A full risk assessment of a site can be obtained by applying the IEC 62305 series of standards which includes a systematic approach for the application of structural and electrical protection. The following is a simplified analysis of the recommendations for electri-cal protection.

Lightning Flash Density (Ng)Lightning flash density gives a statistical measure of lightning flashes per square kilometre per year (Ng). Obviously the risk of lightning related damage increases in areas with a higher lightning flash density. Approximately 70% of all lightning occurs in tropical regions with a total of 1.4 billion flashes per year.

Lightning flash density (Ng) recorded between 1995 and 2003

Source: NASA/GHRC/NSSTC Lightning Team

Environmental InfluencesThe location of the site and method of delivery of electrical services influences the risk of damage due to lightning activity. Selec-tion of the appropriate surge protection device (SPD) at the point of entry to the site will provide an effective solution for the given environmental risk. It is not economically feasible to implement a lightning protection system to cover 100% of all lightning events. A standard IEC62305 risk assessment aims to reduce the risk of economic loss to one event every 1000 years.

Simplified Risk Assessment

The following is a simplified risk assessment for point of entry protection selection based of the most influential environmental factors. A more detailed analysis can be achieved through a full IEC 62305 risk assessment.

Building has a structural lightning protection Ng between 4-15 or system or Ng greater than 15 Overhead power lines

Type 1 Protection recommended Type 2 80kA Protection recommended

Elevated and isolated building and Ng less than 4 and Ng less than 15 Underground cabling

Type 2 80kA Protection recommended Type 2 40kA Protection recommended

Power protection - Type 1

Type 1 (or EN61643-11 Class I) protection devices are designed for point of entry installations where there is a high risk of a direct strike. Buildings that utilise a form of structural protection provide a low resistance path for lightning current to ground and are therefore more likely to receive a direct strike. Buildings in areas with a lightning strike density (Ng) greater than 15 strikes per km2 per year are also more likely to receive a direct strike.

Power ProtectionNovaris offers both power protection and signal line protection devices. Part of the systematic approach to surgeprotection is to ensure that all power and signal lines entering or exiting a premises have surge protection applied to them. This defines a protec-tion boundary at the edge of structure.

Spark Gap TechnologyDue to the long duration and level of energy contained in a 10/350µs direct strike waveform, the protection components used to redirect the surge energy have to be very robust. The Bender Type 1 protection products utilise spark gap technology to provide a very low resistance path for the surge current. The disadvantage of spark gap technology is that the arc takes time to establish, resulting in a higher residual voltage (Up). It is recommended to install secondary MOV based surge protection (Type 2) at the distribution level to reduce the voltage exposure of sensitive equip-ment.

10/350 (Red waveform)The waveform that simulates a direct strike is the 10/350µs. 10µs is the length of time required to reach 90% of the maxi-mum current and 350µs is the length of time for the current flow to fall back to 50% of maximum. The 10/350µs waveform is intended to represent the worst case direct lightning strike and contains approximately 17 times the energy of an equiva-lent peak 8/20µs waveform.

Power protection - Type 2

Type 2(or EN61643-11 Class II) protection devices are designed to protect installations where a direct strike is unlikely to occur. Buildings that do not require structural lightning protection or buildings in low lightning regions are much less likely to receive a direct strike to the point of power entry on the building. Type 2 surge protection is required as secondary protection downstream of spark gap based Type 1 protection.

Metal Oxide Varistor TechnologyThe Metal Oxide Varistor’s (MOV) electrical properties are similar to those of a semi-conductor. The component is in a high impedance state when a voltage lower than the ‘clamping voltage’ rating is applied. The component instantaneously changes to a low impedance state when the ‘clamping voltage’ is exceeded. This re-directs a majority of the surge current away from the load whilst reducing the surge voltage exposure. The advantages of MOV technology are its lower residual voltage (Up), instantaneous reaction time and no follow on current (Ifi) tripping circuit breakers.

8/20 (Blue waveform)The waveform that simulates the attenuated indirect strike or switching surges is the 8/20µs. 8µs is the length of time required to reach 90% of the maximum current and 20µs is the length of time for the current flow to fall back to 50% of maxi-mum. The 8/20µs waveform represents the majority of surges to which a power system will be exposed.

Power protection - Type 2 single and three phase

Type 2 (or EN61643-11 Class II) protection devices are designed to protect installations where a direct strike is unlikely to occur. Buildings that do not require structural lightning protection or buildings in low lightning regions are much less likely to receive a direct strike to the point of power entry on the building. Type 2 surge protection is required as secondary protection downstream of spark gap based Type 1 protection.

Metal EnclosuresDuring a surge the Metal Oxide Varistor (MOV) components change to a low impe-dance state to pass the surge current. The combination of this current and the residual MOV resistance can generate a substantial amount of heat. Additionally, temporary overvoltages can cause the MOVs to fail to a low impedance state where they start to conduct AC current, which also generates heat. To reduce the risk of heat damage from failed MOVs, Bender Type 2 surge protection devices are housed in substantial metal enclosures. This reduces the instantaneous heat exposure and diminishes the risk of burning.

Active AlarmsNovaris Type 2 surge protection devices utilise active alarm technology. This technology requires power from the incoming phases to activate the LED indication and alarm relay within the device. The advantage of active monitoring is that the alarms respond to multiple failures that could impede the surge protection installation.

Surge component monitoring: If a MOV segment degrades the segment LED will turn off and changes the alarm state, alerting the operator that the device needs to be replaced.

HRC fuse monitoring: A large surge or a short circuit failure of the MOV can cause the protection fuse to blow. The alarm monitors the continuity of the fuse which in turn monitors the SPD’s connection to the circuit.

Phase failure monitoring: The alarm and indication will change state in the case of a phase failure which can suggest a loose connection or more serious issues upstream.

NSG Spark Gap DivertersPower protection Type 1

NSG Spark Gap Diverters for point of entry protection at main switchboards where direct strike protection is required.

Multilayer Carbon Disc TechnologyCarbon disk spark gaps are a robust and proven technology designed to handle long duration surges. The low resistance design minimises the energy dissipation within the device.

Sealed EnclosureThe Novaris spark gap diverters are a sealed unit and do not exhaust hot ionised gas into the switchboard.

Note: It is highly recommended to install MOV based protection at the first layer distribution when using spark gaps for primary protection due to the arc establishment time of spark gap technology.

Monitoring and control protection

The Novaris NSL range of signal line protectors provide multistage protection for most physical process control protocols. Their design utilises a gas discharge tube front end to provide 10kA of common mode protection with finer grade protection components delivering very low residual voltage during a surge.With an electrically sealed width of only 7mm per signal pair, the NSL enables economical use of cabinet real estate and also accommo-dates straightforward upgrades of existing feed through terminal block installations. The design is modular with 2 standard bases and a range of pluggable modules appropriate to the physical protocol being protected.The NSL utilises the DIN rail mount as a low impedance earth connection and provides Earth/Shield terminals for convenient equipment and shield grounding.

Signal Line Protection Novaris offers both power protection and signal line protection devices. Part of the systematic approach to surgeprotection is to ensure that all power and signal lines entering or exiting a premises have surge protection applied to them. This defines a protec-tion boundary at the edge of structure.

Base OptionsThe two base options in the NSL range are the NSLDIN/G (G base) and the NSLDIN/EC90 (EC90 base). The G base has a direct connection between the earth provided by the DIN rail, the earth terminals on the unit and the surge protection module earth. The EC90 base contains an isolation gas discharge tube between the shield terminals / surge protection module earth, and the DIN rail.

The EC90 base provides 2 functions: Ground Loop Isolation: Isolating the surge protection and shield from the ground

prevents current flow on the shield and stray voltages being injected onto the signal pairs.

Equipment Bonding: During a surge the Gas Discharge Tube will fire, bonding the earths of the two sites together through the larger shield conductor, reducing the earth potential difference between the sites. The recommended installation technique is to use G bases for protection of the central marshalling cabinet and EC90 bases for all remote equipment. This ensures the installation feeds from the same earth reference point.

23

Field instrument protection

The Novaris NSLT is a threaded signal line protector designed to be installed in a spare process connection gland within a field instru-ment enclosure. These devices are designed with 10kA of common mode protection and MOV based transverse mode components. This combination provides an excellent level of protection in a very convenient form factor for signals up to 200V.The NSLT protection devices are available in 2, 3 and 4 wire variants, suitable for the appropriate process control transmitter signal configuration.

The NSLT also supplies a shield connection wire which provides 2 functions: Ground Loop Isolation: Isolating the shield from the ground prevents current flow on the shield, reducing induced noise onto signal

pairs. Equipment Bonding: During a surge the Gas Discharge Tube will fire, bonding the earths of the two sites together through the larger

shield conductor, reducing the earth potential difference between the sites.

The NSLT is available with enclosures designed for M20 x 1.5 and ½” NPT glands.

Power supplies protectionThe Novaris NSSP6A is a series slimline ELV power protection device for load currents up to 6A. These SPDs are designed to provide 9.6kA of common mode and 4.8kA of transverse mode protection utilising MOV technology.

With an electrically sealed width of only 7mm per signal pair, the NSSP6A enables economical use of cabinet real estate and also accom-modates straightforward upgrades of existing feed through terminal block installations.

The NSSP6A utilises the DIN rail mount as a low impedance earth connection and provides earth terminals for convenient equipment grounding.

It is recommended to use an EC90 base for the field installation end of the cable to prevent ground loop issues.

High Current slimline surge protection devices (SPDs) provide surge protection for most twisted pair signaling schemes.

Load current up to 6 AThe NSSP6A series surge protectors complement the SL range for applications of load currents up to 6A. Typical applications may include power supplies, digital outputs and other low voltage requirements up to 6A.

Two different earthing optionsWith two different base options the NSSP6A protectors offer either direct earthing via DIN rail, for the most effective, low impedance earth connection (-G base) or a connection via GDT to the DIN rail, offering isolation under normal conditions and equipotential bonding during a surge (-EC90 base).

Slimline pluggable modulesThe plug-in design provides simple and rapid replacement and testing - no rewiring needed. This also provides a convenient method of field equipment isolation if required.

Product Series Base optionTop

NSL-7v5 - [*]

Process Control Protection for most twisted pair signalling schemes. Ideal for the protection of PLCs, fire and security systems, telecommunications and telemetry systems, railway signalling, SCADA and other industrial monitoring and control equipment.

Multistage failsafe designA high energy gas discharge tube (GDT) as primary protection plus series impedance and secondary components provide very robust surge protection with high transient suppression offering low let-through voltages.

Two different earthing optionsWith two different base options the NSL protectors offer either direct earthing via DIN rail, for the most effective, low impedance earth connection (-G base) or a connection via GDT to the DIN rail, offering isolation under normal conditions and equipotential bonding during a surge (-EC90 base).

Slimline pluggable modulesThe plug-in design provides simple and rapid replacement and testing - no rewiring needed. This also provides a convenient method of field equipment isolation if required.

NSLT x - [SIG] - [THREAD]Product Series Thread1 Pair / 3 / 4 Wire Voltage Options

Threaded instrument protectors provide surge protection for most twisted pair signalling schemes and are designed to be installed directly at the field equipment providing protection against induced surge and transients.

M20 and 1/2"NPT threadsThe threaded enclosure provides an easy installation by directly screwing into a free cable entry on the instrument. Common thread types such as M20 x 1.5 and 1/2" NPT threads are accomodated for. Other threads are available by request.

Multistage designThe multistage design provides a high energy gas discharge tube (GDT) as primary protection for common mode disturbances, commonly associated with lightning strikes and power system earth faults and a secondary metal-oxide varistor clamping stage across the signal lines. This combination provides very robust surge protection with high transient suppression and low let-through voltages. In addition protection is provided for cable screens which may be open circuit at the instrument.

SLT-Y AdapterWhere a field instrument has no free cable entry Novaris can supply a Y-piece adapter to accommodate the threaded instrument protector and cable gland. The SLT-Y is available in the same thread types as the SLT protectors.

Cat6 and PoE RJ45 Network Surge Protection products are specifically designed for the protection of twisted pair Ethernet systems with a combination of rugged and fine grain protection elements.

10kA Front End Protection & Low Impedance Secondary ProtectionThe RJ45-CAT6 and RJ45-PoE protection products employ a 10kA Gas Discharge Tube per signal pair to dissipate the energy associated with large common mode surges.The silicon based secondary protection element used on each signal pair provides exceptional protection for your equipment whilst allowing network speeds up to Gigabit/1000BaseT.

PoE, PoE+, High Power PoE and beyondThe Novaris PoE protection devices are designed to handle up to 1 A of current per signal pair at up to 80VDC. This combination allows for Gigabit PoE systems with 4 pair power up to an outstanding 160W.

UTP and STP cabling compatibleNovaris network protection products utilise shield pass through connectors and metal bodies to allow for uninterrupted shielded network spans. The RJ45-1CAT6-EC90 option is necessary for earth isolation at the remote end of a network. This prevents current loops from appearing on the network shield.

Lead Length

The performance of a shunt connected (in parallel with load) surge protection device is highly dependent on the installation practices used. The residual voltage of all shunt connected surge protection devices is measured directly at the terminals of the device during testing. This gives a relative gauge of performance but does not reflect the device’s installed performance.

The length of wire used to connect the surge diverter to the power feed needs to be kept as short as physically possible during installa-tion to reduce the voltage drop on either side of the diverter. The resistance of the cable generates a small part of this voltage drop but the majority is caused by the inductance of the cable (between 0.5-1.5uH per meter).

The voltage drop due to this inductance can be calculated using the following formula: V=L × di/dt

Additional Technical information

Keeping the connecting lead lengths as short as possible will ensure the surge protection installation is operating optimally.

Where the voltage drop across the cable equals the inductance multiplied by the change in current over time. While the induc-tance of the cable is very small, during a surge the change in current over time is extremely large.The example above shows a relatively small 9kA surge with a change in current on the rising edge of 1kA/us or in SI units 1,000,000,000 Amps/second.For the above surge we see a voltage drop of 700V per meter of cable in addition to the SPDs residual voltage.

41

Conversely HRC fuses contain a flat strip of current limiting metal which melts when the current exceeds the threshold rating. This results in a level of inductance pro-portional to a wire conductor the length of the fuse and fitting. Bender Type 2 SPDs have active alarm monitoring which monitors the state of the HRC fuse as well as the surge protection components.

The maximum fuse rating of a Bender Power SPD is provided in the technical datas-heet and on the product label. It is recommended to select a fuse rating that is no higher than this maximum and 30% lower than the rating of the upstream breaker or fuse. This is to ensure that in the unlikely event of surge protection failure, that the surge protection fuse blows and not the upstream breaker. This secures the site’s power delivery, even in the event of a SPD failure.

Overcurrent Protection

Bender only recommends the use of HRC fuses for overcurrent protection of their shunt (parallel) connected surge protection devices. Circuit breakers are designed with a coil that acts as an electromagnet. This switches the circuit breaker when the load current exceeds the threshold rating. The coil has a relatively large level of inductance which when exposed to the change in current during a surge, creates a substantial voltage drop.

Surge Protection Coordination

The performance of a surge protection scheme for a site is greatly enhanced when multiple stages of surge protection are used. Bender recommends at least 2 stages of protection, especially for impulse category 1 equipment which is designed to withstand an impulse of only 1.5kV. The first benefit of multiple surge protection stages is SPD coordination. When the high voltage of the surge is applied to the surge protection device it changes from a high impedance state to a low impedance state. The residual impedance combined with the current passing through the device, or the spark over voltage, determine the surge protector’s residual voltage. The point of entry device passes the majority of the surge current due to the impedance of the wire separating each stage of SPDs. Because the secondary SPD passes less current, the residual voltage is less. This ensures the residual voltage will be less than the impulse category of the equipment especially for surges higher than the nominal surge current (In) of the SPD.

Pointof

EntrySPD

2ndLevelSPD Lo

ad> 10m

The other benefit of multiple stages of protection is redundancy. If the point of entry protection device fails, the secondary pro-tection device will keep the circuit protected. This means the equipment is not exposed while the primary protection is replaced.

42

A common mode surge is one that appears as a voltage on all lines with respect to earth. These generally cause catastrophic breakdown between the equipment and its earth.Earth potential rises and induced voltages are made up predominantly of the common mode component. All surge types gene-rally have most of their energy in the common mode. This is why Bender products focus most of the protection energy to protect against common mode surges. A transverse mode surge appears as a voltage difference between the incoming lines. This is what causes damage to the input stages of electronic equipment as the electrical load appears across these incoming lines. The transverse mode component of the surge is generally a lower energy component caused by loading imbalances during a surge and switching surges. Protecting the input stage is where the low residual voltage of the Bender surge protection series is important.

Common Mode vs Transverse Mode

There are 2 modes of surge that Bender SPDs are designed to protect against. They are common mode and transverse mode. The effects of a surge in the field are a combination of these two modes.

Signal Line Protection – Protecting both ends

The main types of surge affecting signal line equipment are earth potential differences and induced surges. The major component in these surges is a common mode difference bet-ween the lines and earth. To protect against this the protection device provides a low impedance path that reacts at a voltage lower than the insulation breakdown voltage of the equip-ment. If only a single SPD is installed, the surge exposure will increase because of this lower voltage reaction.

Common Mode Transverse Mode

By installing surge protection at both ends of the signal cable: The surge current has a clear path to ground at both ends The effective protection on the cable is doubled The shield wire can be used as a temporary equipotential bond during the surge The equipment at both ends is effectively protected due to their proximity to the SPD.
