INTRODUCTIONCompany ELEKTROMEHANIKA & BB d.o.o. was established fromrecent company ElektroMehanika Oblak, which history reaches in1983. From beginning it was a family company, which grows nowdays into bigger market player, still with a 100% private ownership.The main production based on manufacturing of over voltageprotection for low voltage systems. All products comply withIEC/EN 61643-11.

COMPANY VISIONAs small flexible company our goal is to become an importantplayer on low voltage over voltage protection all over theEuropean markets. Expending our range of products in way ofcustomer’s requirements and market necessities achieve successand constant growth for the company and for our employees,customers as well and for everything surrounds us.

COMPANY STRATEGYTo conquer different markets of our customers, partners, suppliersand consequently make constant development of the company.Make EBB brand one of the strongest and most recognized all overthe Europe. With different brandings, conquer confidence of bigEuropean companies and become main supplier for over voltageprogram. Ensure very high level of quality, follow the markettrends and IEC requirements and mostly with optimization levelof the production process be able to offer competitive prices.

GENERAL

- 4 -

A transient overvoltage protection device acts as a ground inparallel with the equipment to be protected. When the supplyvoltage is lower than its activation voltage, the protector acts as ahigh-impedance element so that no current flows through it.

By contrast, when the supply voltage is higher than the activationvoltage, the protector acts as an element with an impedance closeto zero, leading the overvoltage to earth and preventing it fromaffecting the receivers.

In our daily lives most obvious consequences of damage causedby over-voltage is the destruction of electrical equipment, as inprivate house following are specifically; TV, Video, Hi-Fi, computers,telephone and fire system, monitoring equipment, etc.

In case of unprotect equipment against surges following failure ofsuch equipment can certainly incurs; loss of computer data,damage of heating / cooling water or air systems, damage ofelevators, etc.

CAUSES FOR OVER VOLTAGES

- 5 -

The largest voltage peaks in the low-voltage systems are caused byatmospheric discharges. The high energy is content when a direct strikehit the external over voltage protection system or a low-voltage over-head line. Without internal over-voltage protection the strike usuallycauses a total outage of the connected equipment and damage of theinstallation. Induced voltage peaks in building installations and energyor data supply cables can also many times reach the nominal operatingvoltage. Switching operation on the power distribution system can resultswitching surges, as switching of transformers, motors or disconnectionof circuit breakers or cut outs (i.e in the distribution circuits) lead to overvoltages that penetrate the user’s building, which in fact do not cause such high voltage peaks as atmospheric discharges but occurmuch more frequently and can result in immediate system failure. Practical field explains that switching surges reach two to threetimes the operating voltage; meanwhile atmospheric discharges can sometimes reach 20 times the nominal voltage value andtransport high energy content. A number of different protection measures are required. These depend on the exact cause and/orimpact point of the atmospheric discharge.

We’re talking about direct atmospheric discharge, whenlightning strike hits external protection system of roof orlow-voltage over-head line. Usually the potential increasecauses the lightning current to be split over the building’searthing system and also over the power supply systemsand data cables to the adjacent earthing systems.

Switching surges are caused by switch-on and switch offoperations (switching inductive or capacitive loads) andby interrupting short-circuit currents. Particularly whenproduction plants, lighting systems, bigger electromotors or transformers are switched of lead to overvoltages that penetrate the user’s building. Significantly,the closer the building is to a generating station thehigher Surge may occur.

We’re talking about indirect atmos-pheric discharge, as a cause of directlightning strike in radius approx. 2km.

TERMINOLOGY OF ELECTRICAL CHARACTERISTICS

- 6 -

Surge arrester or SPD A device composed of at least one non-linear component that is intended forlimiting surge voltages on electrical equipment by diverting or limiting surgecurrent.

Nominal discharge current In Crest value of the current through the SPD having a current waveshape 8/20.It is used to determine Up value.

Voltage protection level Up Maximum voltage to be expected at the SPD terminals due to an impulsestress with In value for Class I & II.

Maximum discharge current Imax Crest value of a current through the SPD having an 8/20 waveshape andmagnitude according to the manufacturing specification. Imax is equal to orgreater than In.

Impulse discharge current for class I test Iimp Crest value of a discharge current through the SPD with specified chargetransfer Q and specified energy W/R in the specified time.

Class I SPD Class I is designed to discharge high current 10/350 waveshape. This isfirst protection in buildings.

Class II SPD Class II is designed to discharge high current 8/20 waveshape. This issecond protection in buildings.

Maximum continuous operating voltage Uc Maximum r.m.s. voltage, which may be continuously applied to the SPD`smode of protection.

Temporary overvoltage test value Ut Test voltage applied to the SPD for specific duration tT, to simulate the stressunder TOV conditions.

PRODUCT SELECTION

Correct choice of over voltage arresters depends on a several criteria`s defined whencalculating the atmospheric discharges. Correct decision consequently influenceon the complete level of protection. During the project designing all parameters inthis preceding guide, sections under installation rule, must be considered, as wellmakes us better understanding of complete over voltage theory. For properselections of SPD must it is necessary to choose next parameters:

1. Class acc. IEC/EN 61643-11 (Class I, I+II, II, III)Proper protection always consists with three step protection. Class I SPD`s arebuild as first protection (where supplying cable comes into the building), ClassII SPD`s are installed as a second protection (is installed parallel between firstand third protection), Class III SPD`s are installed directly before equipment.

2. Maximum operating voltage UcDuring the calculation, it`s not allowed to use overvoltage arrester with lower Ucvalue, as maximum operating voltage of the system Uc voltage should be at least20% higher than Un.

3. Protection level UpWhen choosing the protection level Up, you must consider the level ofovervoltage that the equipment to be protected can withstand. The lower thevalue of Up, the better the protection.

4. Network`s earthing systemIn electricity supply systems, an earthing system or grounding system is circuitrywhich connects parts of the electric circuit with the ground, thus defining theelectric potential of the conductors relative to the Earth’s conductive surface.The choice of earthing system can affect the safety and electromagneticcompatibility of the power supply. Please see page with EARTHING SYSTEMS.

OVER VOLTAGE ARRESTER FOR POWER LINESCompany EBB offers overvoltage arresters PZ-A withoperating voltages Uc=280V, 440V, 500V, 660V and nominaldischarge currents In=5kA and 10kA. PZ-A arresters areprovided to protect low voltage equipment in AC networksagainst direct, indirect and switching overvoltages. They areused in overhead lines in electro distribution. It isrecommended that an arrester is installed on every 500m ofa line.Arrester uses ZnO varistor as main component and its upperconnection has a 19mm/M8 screw. The grounding connectionon the side of the arrester has a clamp for connection for fourarresters in line. Arrester is encapsulated in a UV resistantpolyamide housing (PA66GF30). This provides a very goodprotection against weather influences and suitable dielectricstrength. There are three types of arresters; one is designedwith signalization and two without it.
