PLANNING OF SURGE PROTECTIVE SYSTEMS

II

General view of surge protective systems and their necessityImmensely fast technological advancement in all fields of science and culture has introduced a lot of devices, even there, where we recentlycouldn't have imagined them. There is a lot of information from all over the world, which has to be correctly linked together and at the sametime swiftly transmitted from one place to another. In today's technical and economical world this is a generally recognized demand, which wecannot reject.It is not our mission to discuss the technological revolution, but we would like to follow and understand it and above all share our knowledgeand experience from the field of surge protective elements and contribute to technical improvement as a whole.In this context it is necessary to see protective devices as a solid shield, which protects objects from strong external interferences, such aslightning strikes.The purpose of installing surge protective modules is that with correct and functional protection in suitable places, a partial or total collapse ofthe system is prevented.

Causes of over-voltagesOver-voltage originates from:

- Atmospheric discharges, which can cause a direct strike in a particular system or as a consequence of induction, transferred to the nearby objects;- Over-voltage due to switching (consequence of connecting and disconnecting of consumers);- Errors in power supply systems (ground contacts) or coincidental connection at different power supply, information and telecommunication systems;- Electric pulls (electrical train, tram, metro …)

Damage statisticsDamage statistics periodically issued by the insurancecompanies, show problems and typology of damages.The largest part of damages on electrical devices is ofover-voltage origin and ranges from 27 % to 35 %regarding the headquarters and territory of insurancecompany.

Terminology for better understanding and selection of over-voltage protection

1. Surge Protection Device (SPD): devices for overvoltage limiting2. Maximum allowed voltage (Uc): maximum allowed (AC or DC) and connection voltage on SPD. At the same time this is its rated voltage.3. Protective voltage level (Up): voltage that occurs on SPDs connectors at presence of exact shape and amplitude impulse4 Residual voltage (URES): peak voltage value at load of SPD with striking current5 Occasional over-voltage (UTOV): over-voltage that occurs in power supply conductor due to system's non linearity or ground contacts. It is

characteristic for its relatively long duration (up to 5s, in some cases up to few hours). It is the most frequent cause for destruction of SPD.6 Impulse current (Iimp): peak value of wave current 10/350 µs. It is used for classification of class I SPDs.7 Rated leak current (In): peak value of wave current 8/20 µs. It is used for classification of class II SPDs.8 Maximum discharge current (Imax) for class II test: crest value of the current through the SPD having an 8/20 waveshape and magnitude

according to the test sequence of the class II operating duty test. Imax is greater than In.9 Combined wave: it is carried out with voltage wave generator 1,2/50 µs. In case of short circuit it turns to wave 8/20 µs. Voltage impulse

is symbolized as Uoc and current at short circuit as Isc. Combined wave is used for classification of class III SPDs.10 Casing protective level (IP): is level of casing protection against invasion of foreign objects or water against parts of the machine that are

under electric power.11 Circuit breaking device of SPDs: is a device that switches off the protective element from the line in case of thermal escape. At the same

time it is also an indicator of damaged SPDs.12 Following current (IF): current, which runs from power supply system after the lapse of striking wave or after reaction of SPDs.13 Flux protection (e.g. fuse): is a part of electrical installation, placed in front of SPDs. It serves as protective element in case of inability to

react or damage of circuit breaking device of protective element.14 Voltage strength (Uw): according to voltage strength devices are classified into following four classes: 1500 V, 2500 V, 4000 V in 6000 V

considering the direction of electricity flux (classes are determined under IEC 60664-1).15 MB: Main distribution board16 SB: Secondary distribution board17 SA: Socket close to apparatus

Atmospheric dischargesAtmospheric discharge is transient, a discharge with high current intensity, which is caused by charge transition between earth and a cloud,between clouds or between cloud and earth.

More than half of all strikes take place between the clouds, which is called IC (inter-cloud) discharge. The discharge cloud-earth, also called CD(cloud-ground) was a subject of many studies, because it is of life importance (e.g. as a cause of death, harmful influences on power supply andtelecommunication lines etc.).

There are two different modes of CG atmospheric discharges:

1. Negative charge towards positive ground (negative atmospheric discharge),2. Positive charge (ground) towards negative cloud (positive atmospheric discharge).

Up to 90 % of all atmospheric discharges can be ascribed to negative ones and approximately 10 % to positive ones.

Lightning densityLightning density towards ground is defined as a number of lightning strikes towards ground per square kilometre per year and should bedetermined with lightning allocation system measurement.

If the lightning density towards ground (Ng) isnot given, we can estimate it with the followingequation:

Ng = 0,04 . Td1.25 /km2/per year

Ng = number of expected atmospheric dischargesper year per square kmTd = number of stormy days per year; taken fromisokeraunic maps

(Source: EN 61024-1)

Number of stormy days per year (Td) in Slovenia

Regarding the lightning threat on macro levelSlovenia can be divided into three regions:

1. Ng = 2.5 - 4

Comprises a triangle: Ljubljana - the Alpineworld - the Adriatic sea and is coloured asa region of great threat.

2. Ng = 1.5 - 2.5

This region comprises central Sloveniabetween the Ljubljana basin and Maribor. Itis classified into a moderately threatenedregion.

3. Ng = 1 - 1.5

This category comprises the Drava plainwith the Pomurje region. It is recognisedas a threatened region.

IV

Expected atmospheric discharge magnitudesMaximum atmospheric discharge magnitudes occur from a few 10 kA to 200 kA. See graph 1 which depicts statistical data on intensity amplitudeat discharging.

Comment: the greatest certainty is that the amplitudes of atmospheric discharges are in the range between 10 - 35 kA.

Threat and admissible damage prevalence due to atmospheric discharges on objects

The purpose of protection against lightning is to minimize the damage risk under admissible maximum level. This means, that it is necessary tofulfil the following requirements:

R ≤ RT

RT = tolerable level riskR = total risk

Damages caused by atmospheric discharges are as follows:

1. loss of human lives (R1);2. unacceptable mains failures of public power supply systems (R2);3. irretrievable destruction of cultural heritage (R3);4. loss of economic values (R4).

INSTALLATION AND CHOICE OF SPD

VI

a) NetworksIn accordance with IEC 364-4-41 (1992) a low voltage distribution system is usuallycharacterized from electricity source to terminal equipment with the following:

- grounded power supply source (e.g. low voltage connection of local network transformer);- grounded system of exposed conductible parts in consumer electrical installations.

Through this three basic types of systems could be defined as distribution systems:- TN system;- TT system;- IT system.

Used abbreviations have the following meaning:

The first letter describes grounded system of power-feeding electricity source.T - direct grounding of power supply source single point (primarily connecting point of

transformer winding);I - isolation of all active parts from ground or connection of single source point of

electricity to ground over some sort of impedance.The second letter describes grounded system of exposed conductible parts of electrical installation

T - exposed conductible part is directly grounded independent of eventual existinggrounded feeding point

N - exposed conductible part is directly connected to grounding electrode (grounding resistor)Further letters describe an arrangement of neutral and protective conductors

S - neutral and protective conductor are separatedC - neutral and protective conductor are connected

Hence it follows that there are three possible TN systems: TN-S, TN-C and TN-C-S

The following protective devices can be installed in the different systems:- Over-current protective device,- Residual protective device (r. c. d.)- Insulation monitoring device- Fault-voltage-operated protective device

As mentioned before, it is necessary to co-ordinate the type of system grounding and thecharacteristics of protective conductors and protective devices. The following protectivedevices are applicable in the different systems:

TN-S system

TN-C system

TN-C-S system

TT system

IT system

TN System- Over-current protective device;- Residual current protective device.

TT System- Over-current protective device;- Residual current protective device,- Fault-voltage-operated protective device.

IT System- Over-current protective device;- Residual current protective device,- Insulation monitoring device- Fault-voltage-operated protective device

METHODS AND DIRECTIONS FOR PLANNING SURGE VOLTAGE SYSTEMS IN NN INSTALLATIONS

IX

1. We determine the protective zone (as per IEC 62 305 Ed. 1) and the point of crossing. Thepoints of crossing in the protective zone and the installation points MB, SB, SA are also theplaces where surge protection devices SPDs are installed.

POINTS OF CROSSING IN PROTECTED ZONESAt point MB (main distribution board) which is at crossing OB/1 and is subject to partialdirect lightning strikes, a class 1 SPD must be installed. Class 1 SPDs are those declared forcurrent arrester pulses 10/350 µs.

2. Determining expected current values depending on typical models.

2.a. Model of exposed structure ( radio base stations, waterworks, RTV transmitter, etc.)Theoretically current sharing in case of direct lightning strike into building

50% - LPS

50% - power supply

IIMP /2 = 200 kA/2 = 25 kAn 4

IIMP /pole = 25 kA

n = number of conductors (for easier calculation the influence of gas, water and other conductors are omitted).

In each conductor a maximum current value of 25 kA is expected.

2.b. Model of two structures (earthing resistance is the same) close together.Theoretically current sharing in case of direct lightning strikeinto building

50 % - LPS

50 % - IIMP = IIMP /2 = 100 kA = 50kA1+ RA 2

RB

IIMP/pole = IIMP = 50 kA = 12,5 kAn 4

With this model we can expect the same distribution in bothstructures and in all conductors and an expected current of12.5kA per conductor.

Legend: MB = Main distribution board; SB = Sub-distribution board; SA = Socket outlet

X

2.c. Model of two structures (earthing resistance is not thesame). Normally the structures are not in close vicinity.

Theoretically current sharing in case of direct lightning strike into building

50 % - LPS

50 % - IIMP = IIMP /2 = 100 kA = 80 kA 11+ RA 1,25

RB

Ipole = IIMP = 80 = 20 kA 1n 4

IIMP = IIMP /2 = 100 kA = 20 kA 21+ RA 5

RB

Ipole = IIMP = 20 = 5kA 2n 4

Model 2.c. is the most common model with characteristic distribution of current, i.e. 40 %in the structure with lower earthing resistance and 10% in the one with the higher resistancewith equivalent distribution of current along the individual conductors.

Depending on model type (2.a, 2.b., 2.c.) it is necessary to determine the closest exampleand accordingly choose the model and maximum expected current/pole.For guidance use the ISKRA catalogue which covers all characteristic values depicted in thethree models.

For TT systems in three-phase systems IN-PE = 4 . IIMP /pole

For single-phase systems IN-PE = 2 . IIMP / pole

3. Establishing in which group of electromagnetic immunity (EMC), according to IEC 61000-4-5,do the protected devices belong.

Arrangement according to IEC 61000-4-5:

Uoc (1.2/50) Isc (8/20)

1 4kV 2kA

2 2kV 1kA

3 1kV 0,5kA

4 0,5kV 0,25kA

Uoc and Isc so are values with which EMC immunity is tested

4. Determining distance ( l ) between protected device and SPD.

0A = direct lightning strike zone0B = partial direct strikes zone0B/1 = installation point of SPD class Il = distance between SPD and protected device

XI

5. Selection of SPD fulfilling the following demands

Uprot ≤ Ui

Uprot = Up + ∆U

Up = protection level of SPD (kV)∆U = inductive voltage dropUi = dielectric strength of device (kV) in accordance with installation category (from 1 to IV)Uprot = voltage sensed by the device

Dielectric values according to category

Category Dielectric strength (kV)I 6 kVII 4 kVIII 2.5 kVIV 1.5 kV

Dielectric strength category must be given by the manufacturer.

The protection level of SPDs also determines the length of the conductors.The length of the conductors influences additional inductive voltage drop as follows:A conductor length of 1m has an inductance of approximately 1µH, which at current steepness of 1kA/µs contributes approximately 1kV.

Influence of conductor length

∆U= L . di––––dt

∆U= 5µH . 1kA––––µs

∆U= 5kV

Therefore the SPD must be installed with the sense of decreasingthe length of connected conductors.

Rule: consider the smallest section of theearthing conductor as follows:

Class I min. 16 mm2

Class II, III min. 6 mm2

or according to the manufacturer'sinstructions, if marked otherwise.

F = fusea, b: length of connection conductors

Example: of correct connection andmaximum length of connectedconductors.

XII

The table allows easier defining of needs for secondary and cascade selection of SPDs.Manufacturers usually give Up values only for In, therefore, the depicted diagram of Up flowis useful data and facilitates work.

6. At point MB (main distribution board) install SPDs class I.They are for effective protection of devices classified in installation categories I and II (6kVand 4kV).Determining distance between SPD installed in point MB (SPD class I) and protected device.If condition Uprot < Ui/2 is not reached, it is necessary to install an additional SPD.

7. At point SB (sub-distributor) an SPD class II is installed. These are installed as protectionagainst induced voltage, which occurs in the installations. The SPDs must comply to theminimum demand In = 5kA; in connection 1+1 between N - PE 10 kA; in connection 3 +1the SPD must withstand 20 kA between N -PE.

SPDs class II can be used only in crossings from zone I/II (always following SPD class I ).

8. Determining distance between SPD (class II ) on point SB and protected devices.

Condition for proper protection:

Uprot2 < Ui/2

In this case the SPD class II has successfully protected installation category III and II.Note: SPDs class II can only be installed if the incoming utilities are within the protected zone OB.

9. At point SA (the point directly in front of the protected device) an SPD class III is installed.They are always installed after the SPD class I and II.

The indicated order of SPD installation is required for attaining effective protection even inthe case of unfavourable installation conditions.

Protection againstthermal runaway:



An overvoltage arrester INPROTEC is distinguished by its small requirement for mountingspace, since for a complete 3-phase systems protection it requires only width of 4 TE.It is used as a protection against partial direct and indirect lightning strikes.This product group comprises 3 different variants: INPROTEC VV, INPROTEC VG andINPROTEC VS.With simple combinations among them, we can build an overvoltage protection for all 4 knownnetwork systems: TT, TNC, TNC-S and IT.It is intended for protection in zones 0 - 1.A

INPROTEC VV contains two separate varistor couplings withtwo disconnection devices - indicators that indicate thedefect.It functions immediately after the defect, regardless of thevaristor coupling in which the defect arises.
