Minor cause, major effect: Damage caused by surge voltages

Our dependency on electrical andelectronic equipment continues toincrease, in both our professionaland private lives. Data networks incompanies, for auxiliary equipmentin hospitals and fire departmentsfor example, are vital for the realtime transfer of information thathas long since been indispens-able. Sensitive databases, e.g. inbanks or media publishers, needreliable transmission paths. It isnot only lightning strikes that posea latent threat to these systems.More andmore frequently, today'selectronic aids are damaged bysurges caused by remote lightningdischarges or switching operationsin large electrical systems. Duringthunderstorms, too, high volumesof energy are instantaneously re-leased. These voltage peaks canpenetrate a building through all -manner of conductive connectionsand cause enormous damage.

What are the consequences ofdamage caused by surges in ourdaily lives?The most obvious one is the de-struction of electrical equipment. Inprivate households, these arespecifically: TV/entertainment systems Telephone system Computer systems, stereo sys-

tems Kitchen appliances Monitoring systems Fire alarm systemsThe failure of such equipment cer-tainly incurs great expense. Whathappens when the following sufferoutage times/ and the possibleconsequential damage: Computers (loss of data), Heating/hot water systems, Lift,garage door and roller

shutter drives, Triggering or destruction of

fire/burglar alarm systems(costs from a false alarm)?

A vital topic perhaps, particularly in

office buildings, because: Can work continue in your

company without a centralcomputer/server?

Was all the important databacked up "in time"?

Growing sums of damageCurrent statistics and estimates ofinsurance companies show: Dam-age levels caused by surges ex-cluding consequential or outagecosts long since reached drasticlevels due to the growing depen-dency on electronic "aids". It's nosurprise, then, that property insur-ers are checking more and moreclaims and stipulating the use ofdevices to protect against surges.Information on protection mea-sures is contained, e.g. in DirectiveVDS 2010.

Creation of lightning discharges

Creation of lightning discharges: 1 = approx. 6,000m, approx. 30 C, 2 = approx. 15,000m, approx. 70 C

Discharge typesSome 90% of all lightning dis-charges between a cloud and the-ground are negative cloud-earthstrikes. The lightning begins in anegatively charged area of thecloud and spreads to the positivelycharged surface of the earth. Addi-tional discharges are divided into: Negative earth-cloud strikes Positive cloud-earth strikes Positive earth-cloud strikes.Themost common discharges ac-tually occur within a cloud or be-tween different clouds.

Creation of lightning dischargesWhen warm, damp air massesrise, the air humidity condensesand ice crystals are formed at -great heights. Storm fronts can oc-cur when the clouds expand toheights of up to 15,000 m. Thestrong upwind of up to 100 kilo-metres per hour causes the lightice crystals to enter the higherarea and the sleet particles enterthe lower area. Knocks and frictioncause electrical discharge.

Load distributionTypical load distribution: Positive at the top, negative in

the centre and weakly positiveat the bottom.

Positive charges can also befound in the area near the-ground.

The field strength required totrigger lightning is dependenton the insulating ability of theair and is between 0.5 and 10kV/cm.

Charge distribution: 1 = approx. 6,000m, 2 = Electrical field

Negative and positive charges: 1 = Sleet, 2 = Ice crystals

Negative and positive chargesStudies have proved that the sleetfalling down (area warmer than15 C) has a negative chargeand the ice crystals being thrownupwards (area colder than 15C) has a positive charge. Thelight ice crystals are carried intothe upper areas of the cloud bythe upwind and the sleet falls tothe central areas of the cloud. Thisdivided the clouds into the threeareas: Top: Positively charged zone Centre: Weakly negative

charged zone Bottom: Weakly positive

charged zoneThis separation of charges forms avoltage in the cloud.

What are transient surges?

Transient surge voltages: 1 = Voltage drops/short interruptions, 2 = Harmonic waves due to slow and fast voltage changes, 3 = Temporary voltage in-creases, 4 = Switching surges, 5 = Lightning surges

Transient surge voltages are briefvoltage peaks lasting microsec-onds, whichmay be amultiple ofthe attached mains nominal volt-age.

The largest voltage peaks in thelow-voltage consumer network arecaused by lightning discharges.The high energy content of light-ning surges when a direct strikehits the external lightning protec-tion system or a low-voltage open-wire line usually causes withoutinternal lightning and surge protec-tion total outage of the connect-ed consumers and damage to theinsulation. Yet induced voltagepeaks in building installations and

energy or data cable supply ca-bles can also reach many timesthe nominal operating voltage.Switching surges, too, which infact do not cause such high volt-age peaks as lightning dischargesbut occur much more frequently,can result in immediate systemfailure. As a rule, switching surgesamount to twice to three times theoperating voltage, lightning surges,on the other hand, can sometimesreach 20 times the nominal volt-age value and transport a high en-ergy content. Often, failures occuronly after a time delay as the ag-ing process of electronic compo-nents in the affected devices trig-gered by smaller transient surges

causes insidious damage.A num-ber of different protection mea-sures are required. These dependon the exact cause and/or impactpoint of the lightning discharge.

What pulse forms are there?

Pulse types and their characteristics: Yellow = pulse shape 1, direct lightning strike, 10/350 s simulated lightning pulse, red = pulse shape 2, remotelightning strike or switching operation, 8/20 s simulated lightning pulse (Surge)

High lightning currents can flow tothe ground during a storm. If abuilding with external lightning pro-tection receives a direct hit, a volt-age drop occurs on the earthingresistor of the lightning protectionequipotential bonding system,which represents a surge voltageagainst the distant environment.This rise in potential poses a threatto the electrical systems (e.g. volt-age supply, telephone systems,cable TV, control cables, etc.) thatare routed into the building.Suitable test currents for testingdifferent lightning and surge pro-tectors have been defined in na-tional and international standards.

Direct lightning strike: Pulseshape 1Lightning currents that can occurduring a direct lightning strike canbe imitated with the surge currentof wave form 10/350 s. The light-ning test current imitates both thefast rise and the high energy con-tent of natural lightning. Lightningcurrent arrestor Type 1 and exter-nal lightning protection compo-nents are tested using this current.

Remote lightning strikes orswitching operations: Pulseshape 2The surges created by remotelightning strikes and switching op-erations are imitated with test im-pulse 8/20 s. The energy contentof this impulse is significantly low-er than the lighting test current ofsurge current wave 10/350 s.Surge arrestor Type 2 and Type 3are impacted with this test im-pulse.

Causes of lightning currents

Direct lightning strike into a low-voltage open-wire lineA direct lightning strike into a low-voltage open wire line or data ca-ble can couple high partial lightingcurrents in an adjacent building.Electrical equipment in buildings atthe end of the low-voltage open-wire line are at particular risk ofdamage caused by surges.

Threat value: Up to 100 kA(10/350)

Direct lightning strike into abuildingIf a lightning strike hits the externallightning protection system orearthed roof structures capable ofcarrying lightning current (e.g. roofaerial), then the lightning energycan be arrested to the ground inadvance. However, a lightning pro-tection system on its own is notenough: Due to its impedance, thebuilding's entire earthing system israised to a high potential. This po-tential increase causes the light-ning current to spilt over the build-ing's earthing system and alsoover the power supply systemsand data cables to the adjacentearthing systems (adjacent build-ing, low-voltage transformer).

Threat value: Up to 200 kA(10/350)

Causes of surges

Coupling of surges through localor remote lightning strikeEven if lightning protection andsurge protectionmeasures are al-ready installed: A local lightningstrike creates additional highmag-netic fields, which in turn inducehigh voltage peaks in line systems.Inductive orgalvanic coupling cancause damage within a radius ofup to 2 km around the lightningimpact point.

Threat value: Several kA (8/20)

Switching surges in the low-volt-age systemSwitching surges are caused byswitch-on and switch-off opera-tions, by switching inductive andcapacitive loads and by interrupt-ing short-circuit currents. Particu-larly when production plants, light-ing systems or transformers areswitched off, electrical equipmentlocated in close proximity can bedamaged.

Gradual surge reduction with lightning protection zones

Lightning protection zone con-ceptThe lightning protection zone con-cept described in internationalstandard IEC 62305-4 (DIN VDE0185 Part 4) has proved to bepractical and efficient. This con-cept is based on the principle of -gradually reducing surges to asafe level before they reach theterminal device and cause dam-age. In order to achieve this situa-tion, a building's entire energy net-work is split into lightning protec-tion zones (LPZ = Lightning Protec-tion Zone). Installed at each transi-

tion from one zone to another is asurge arrestor for equipotentialbonding. These arrestors corre-spond to the requirement class inquestion.

Lightning protection zone

LPZ 0 A Unprotected zone outside the building. Direct lightning impacts, no shielding against electromagnetic interferencepulses LEMP (Lightning Electromagnetic Pulse)

LPZ 0 B Zone protected by external lightning protection system. No shielding against LEMP.

LPZ 1 Zone inside the building. Low partial lightning energies possible.

LPZ 2 Zone inside the building. Low surges possible.

LPZ 3 Zone inside the building (can also be the metal housing of a consumer). No interference pulses through LEMP orsurges present.

Zone transitions and protective devices

Benefits of the lightning protec-tion zone concept Minimisation of the couplings

into other cable systemsthrough arresting the energy-rich, dangerous lightning cur-rents directly at the point thecables enter the building.

Malfunction prevention with-magnetic fields.

Economic, well-plannable indi-vidual protection concept fornew and old buildings and re-constructions.

Type classes of the surge protec-tion devicesOBO surge protection devices areclassified in accordance with DINEN 61643-11 into three type class-es Type 1, Type 2 and Type 3(previously B, C and D). Thesestandards contain building regula-tions, requirements and tests forsurge arrestors used in AC net-works with nominal voltages of upto 1,000 V and nominal frequen-cies of between 50 and 60 Hz.This classification enables ar-restors to bematched to differentrequirements with regard to loca-tion, protection level and current-carrying capacity. The table belowprovides an overview of the zonetransitions. It also shows whichOBO surge protectors are to be in-stalled in the energy supply net-work and their respective function.

BET testing centre for lightning protection, electrical engineering andsupport systems

Lightning current test

BET with countless tasksIf only lightning current, environ-mental and electrical testing waspossible at BET up to now, theBET Test Centre is now a compe-tent partner for testing of cablesupport systems. This combinationhas made it necessary to revisethe meaning of the name. If BETpreviously stood for "Blitzschutz-und EMV-Technologiezentrum"(Lightning protection and EMCtechnology centre), since 2009these letters havemeant BET Testcentre for lightning protection,electrical engineering and supportsystems.

Test generator for lightning cur-rent testsThe test generator, planned in1994 and built in 1996, allows theexecution of lightning current testsof up to 200 kA. The generatorwas planned and constructed inconjunction with the Soest Techni-cal College. Due to the intensive

planning and scientific consultationrequired in the construction of thetesting system, this system hasworked without fault for 12 yearsand still meets the current stan-dard testing requirements.Themain load of the testgenera-tor is generated by the testing ofproducts from the TBS productunit. Here, tests to accompany de-velopment are carried out on newdevelopments,modifications of ex-isting OBO products and alsocomparison tests on competingproducts. These include lightningprotection components, surge pro-tection devices and lightning cur-rent arrestors. Tests of lightningprotection components are carriedout according to DIN EN 50164-1,those for sparkgaps according toDIN EN 50164-3 and those forlightning and surge protection de-vices according to DIN EN 61643-11. This is just a small portion ofthe testing standards used fortests in the BET Test Centre.

Lightning currentgenerator Salt spray trough Load test

Testing types for lightning andsurge protectionBoth lightning current tests andsurge voltage tests can be carriedout at up to 20 kV.A hybridgener-ator is used for these tests, whichwas also developed as part of acooperation with the Soest Techni-cal College. EMC testing of cablesupport systems can also be car-ried out using this test generator.All kinds of cable routing and ca-ble support systems of up to 8mlength can be tested without anydifficulties. Tests for electrical con-ductivity according to DIN EN61537 are also carried out.

Simulation of real environmentalconditionsTo carry out standardised tests oncomponents intended for externaluse, they must be pretreated un-der real environmental conditions.This takes place in a salt spraytrough and a sulphur dioxide test-ing chamber. Depending on thetest, the test length and the con-centration of the salt spray or sul-phur dioxide in the testing cham-bersmay vary. Thismeans that itis possible to conduct tests ac-cording to IEC 60068-2-52, ISO7253, ISO 9227 and EN ISO6988.

Testing cable support systemsThe well-known KTS testing sys-tem, newly installed in the BETTest Centre, allows the investiga-tion of the load capacities of anycable support system manufac-tured by OBO. The basis for this isDIN EN 61537 and VDE 0639.In the BET Test Centre, OBO Bet-termann has a testing departmentin which products can be testedaccording to standards, even dur-ing the development phase.

Connection length, V-wiringThe connection cable to the pro-tector is crucial for achieving anoptimum protection level. In accor-dance with IEC installation direc-tives, the length of the branch lineto the arrestor and the length ofthe line from the protection de-vice to the equipotential bondingshould in each case be less than0.5 m. If the cables are longerthan 0.5m, then V-wiringmust bechosen.

DecouplingLightning current and surge ar-restors perform a number of func-tions. These arrestors must beused in coordination. This coordi-nation is guaranteed by the exist-ing line length or special lightningcurrent arrestors (MCD series). Forexample, in the protection set,Type 1 and Type 2 arrestors(Classes B and C) can be usedadjacent to each other.

Example cable length > 5 m No additional decoupling re-

quired

Example cable length < 5 m Use decoupling: MC 50-B VDE

+LC 63 +V20-C Alternatively: MCD 50-B +V20-

C, no additional decoupling re-quired (e.g. protection set)

Minimum cross-sections for thelightning protection equipotentialbonding systemThe following minimum cross-sec-tions should be observed for light-ning protection equipotential bond-ing: For copper, a cable cross-sec-tion of 16 mm2, for aluminium25 mm2 and for iron 50 mm2. Atthe lightning protection zone transi-tion from LPZ 0 to LPZ 1, allthe metallic installations must beincluded in the equipotential bond-ing. Active lines must be earthedusing suitable arrestors.

In the TN-C-S network system, theelectrical unit is supplied throughthe three external lines (L1, L2, L3)and the combined PEN line.Usage is described in DIN VDE0100-534 (DIN EN 61643-11).

Lightning current arrestor Type 1Type 1 lightning current arrestorsare used in the 3-pole circuit (e.g.:3x MC 50-B). The connection is ef-fected parallel to the external lines,which are connected to the PENvia the arrestor. Following consul-tation with the local energyprovider and in accordance withthe VDN Directive, use before the-main meter device is also possi-ble.

Surge arrestor, type 2Surge arrestors of Type 2 are usu-ally used after the split in the PENline. If the split ismore than 0.5maway, the network from here on-wards is 5-line. The arrestors areused in the 3+1 circuit (e.g. V20-C3+NPE). With the 3+1 circuit, theexternal lines (L1, L2, L3) are con-

The ar-restors must be used before aresidual current protective device(RCD), as it would otherwise inter-pret the surge current as a residu-al current and interrupt the powercircuit.

Surge arrestor, type 3Surge arrestors of Type 3 are usedto protect against surges in the de-vice power circuits. These trans-verse surges occur primarily be-tween L and N.A Y circuit protectsthe L and N lines with varistor cir-cuits and makes the connectionsto the PE line through a collectivesparkgap (e.g.: KNS-D). This pro-tection circuit between L and Nprevents surge currents fromtransverse voltages being conduct-ed towards PE, the RCD thus inter-prets no residual current.

In the TN-S network system, theelectrical unit is supplied throughthe three external lines (L1, L2,L3), the neutral cable (N) and theearth cable (PE). In the TT net-work, however, the electrical unit issupplied through the three externallines (L1, L2, L3), the neutral cable(N) and the earth cable (PE).Usage is described in DIN VDE0100-534 (DIN EN 61643-11).

Lightning current arrestor Type 1Type 1 lightning current arrestorsare used in the 3+1 circuit (e.g. 3xMC 50-B and one MC 125-BNPE). With the 3+1 circuit, the ex-ternal lines (L1, L2, L3) are con-nected to the neutral cable (N) viaarrestors. The neutral cable (N) isconnected to the protective earthvia a collective sparkgap.

PC Polystyrene

*The minus values apply only for parts in the quiescent condition withno severe impact stress.There is no plastic that is resistant to every chemical. The agents listedare only a small selection. Plastic parts are especially at risk in thepresence of chemicals and high temperatures. Stress cracks mayoccur. If in doubt, please consult us and/or ask for a detailed chemicalresistance table.Stress crack formation: stress cracks may occur if plastic parts undertension are exposed to chemicals at the same time. Parts made ofpolystyrene and polyethylene are particularly susceptible. Stress cracksmay even be caused by agents to which the plastic in question isresistant in the absence of stress. Typical examples of parts underconstant stress when used as intended: grip clips, intermediatesupports of cable glands, ribbon clips.

The little A to Z of surge protection

100% response lightning impulse voltageThe 100% response lightning impulse voltage is the value of thelightning impulse voltage 1.2/50 s, causing the arrestor to switch. Withthis testing voltage, the surge protection device must respond ten timesto ten loads.

ArrestorArrestors are resources, which primarily consist of voltage-dependentresistors and/or spark gaps. Both elements can be switched in seriesor in parallel or used individually.Arrestors are used to protect other electrical resources and electricalsystems against surge voltages.

Arrestor measured voltage VcFor arrestors without a spark gap, the measured voltage is themaximum permitted effective value of the mains voltage on the arrestorterminals. The measured voltage may constantly be applied to thearrestor without changing its operational characteristics.

Back-up fuse before the arrestorsThere must be a back-up fuse before the arrestors. If the upstream fuseis greater than the maximum approved back-up fuse of the arrestorelements (see technical data of the device), the arrestor must beprotected selectively with the required value.

Cut-off unitThe cut-off unit cuts the arrestor off from the mains or the earthingsystem if it is overloaded, thus preventing a fire risk and also signallingthe switch-off of the protection device.

Equipotential bondingElectrical connection, which brings the bodies of electrical resourcesand other conductive parts to the same or almost the same potential.

Equipotential bonding rail (PAS)A terminal or rail, intended to connect the protective conductor, theequipotential bonding conductor and, if necessary, the conductor forfunction earthing with the earthing cable and the earthers.

Error current protection unit (RCD)Resource for protection against electric shocks and fire protection (e.g.FI protection switches).

Lightning protection equipotential bonding systemThe lightning protection equipotential bonding is a key measure inreducing the risk of fire and explosion on the room or building to beprotected. The lightning protection equipotential bonding is achievedusing equipotential bonding cables or arrestors, which connect theexternal lightning protection system, metallic parts of the building orroom, the installation, the other conductive parts and the electricalenergy and telecommunications systems.

Lightning protection system (LPS)A lightning protection system (LPS) is considered as the entire systemused to protect a room or building against the impact of a lightningstrike. This includes both internal and external lightning protection.

Lightning protection zone (LPZ)Lightning protection zones are those areas in which the electromagneticenvironment of the lightning is to be defined and mastered. At the zonetransitions, all cables and metallic parts must be integrated into theequipotential bonding system.

Lightning surge current (limp)A lightning surge current (lightning current carrying capacity per path) isa standardised surge current curve of the shape 10/350 s. With itsparameters- Peak value- Charge- Specific energyit represents the load from natural lightning currents. Type 1 lightningcurrent arrestors (previously requirement class B) must be able to arrestsuch lightning currents without being destroyed.

Line follow current quenching (lf)The follow current also called network follow current is the currentwhich flows through the surge protection device after an arrestingoperation and is supplied by the network. The follow current isconsiderably different from the continuous operating current. The levelof the network follow current is dependent on the feed line from thetransformer to the arrestor.

Nominal current (ln)The nominal current is the maximum permitted operating current whichmay be run continually through the appropriately labelled connectionterminals.

Nominal discharge surge current (ln)Peak value of the current flowing through the arrestor with the waveshape 8/20. It is used to classify the testing of surge arrestors of Type2 (formerly requirements Class C).

Nominal frequency (fn)The nominal frequency is that frequency for which a resource ismeasured, by which it is called and upon which other nominalparameters refer.

Nominal voltage (Vn)The rated voltage is the voltage value for which a resource is designed.In so doing it might be a direct voltage value or the effective value of asine-form alternating voltage.

Surge protection device (SG)A device intended for the limitation of transient surge voltages andarresting of surge voltages. It contains at least one non-linearconstruction element. In general speech, surge protection devices arealso termed arrestors.

Protection level (Up)The protection level is the highest current voltage value on the terminalsof the surge protection device before response.

Residual voltage (Vres)The peak voltage value, occurring via the terminals of the surgeprotection device during or immediately after the arresting surge currenthas flowed.

Short-circuit resistanceThe surge protection device must be able to conduct the short-circuitcurrent, until it is either interrupted by the device itself or by an internalor external cut-off unit or by mains-side over-current protection (e.g.back-up fuse).

Response time (ta)The response time primarily characterises the response behaviour ofthe individual protection elements used in arrestors. Depending on theslope du/dt of the surge voltage or di/dt of the surge current, theresponse times may vary within specific limits.

SPDSurge protection device.

Surge arrestor, Type 1Arrestors, which, due to their special structure, are able to arrest lightingcurrents or partial lightning currents during direct strikes.

Surge arrestor, Type 2Arrestors, which are able to arrest surge voltages cause by remote ornearby strikes or switching actions.

Surge arrestor, Type 3Arrestors, used for surge protection of individual consumers orconsumer groups and are employed directly on sockets.

The little A to Z of surge protection

Surge voltageA surge voltage is a voltage occurring briefly between conductors orbetween a conductor and the earth, which exceeds the highestpermissible operating voltage value by a long way, but does not havethe operating frequency. It can be created by storms or by earthing orshort-circuits.

Temperature rangeThe operating temperature specifies within which temperature limits theperfect function of the surge protection device is guaranteed.

Transient surge voltage (TOV)Temporary surge voltages are short-term (i.e. temporary) surgevoltages, which may occur due to errors within the medium and low-voltage network.

Transmission frequency (fg)The transmission frequency specifies up to which frequency theinsertion damping of the employed resource is less than 3 dB.

Volume resistance per path, series resistanceThe volume resistance per path specifies the ohmic resistance increaseof the conductor path per wire caused by the use of the surgeprotection device.
