INTRODUCTION The purpose of this International Standard is to identify the requirements for Surge Protective Devices (SPDs) used in protecting telecommunication and signalling systems, for example, low-voltage data, voice, and alarm circuits All of these systems may be exposed to the effects of lightning and power line faults, either through direct contact or induction These effects may subject the system to overvoltages or overcurrents or both, whose levels are sufficiently high to harm the system SPDs are intended to provide protection against overvoltages and overcurrents caused by lightning and power line faults This standard describes tests and requirements which establish methods for testing SPDs and determining their performance The SPDs addressed in this International Standard may contain overvoltage protection components only, or a combination of overvoltage and overcurrent protection components Protection devices containing overcurrent protection components only are not within the coverage of this standard However, devices with only overcurrent protection components are covered in annex A An SPD may comprise several overvoltage and overcurrent protection components All SPDs are tested on a "black box" basis, i.e., the number of terminals of the SPD determines the testing procedure, not the number of components in the SPD The SPD configurations are described in 1.2 In the case of multiple line SPDs, each line may be tested independently of the others, but there may also be a need to test all lines simultaneously This standard covers a wide range of testing conditions and requirements; the use of some of these is at the discretion of the user How the requirements of this standard relate to the different types of SPD is described in 1.3 Whilst this is a performance standard and certain capabilities are demanded of the SPDs, failure rates and their interpretation are left to the user Selection and application principles will be covered in IEC 61643-22 1) If the SPD is known to be a single component device, it has to meet the requirements of the relevant standard as well as those in this standard ––––––––––– 1) Under consideration Page

requirements and testing methods 1.1 General Scope This International Standard is applicable to devices for surge protection of telecommunications and signalling networks against indirect and direct effects of lightning or other transient overvoltages The purpose of these SPDs is to protect modern electronic equipment connected to telecommunications and signalling networks with nominal system voltages up to 000 V (r.m.s.) a.c and 500 V d.c 1.2 SPD configurations The SPD configurations described in this standard are shown in figure Each SPD configuration is composed of one or more voltage-limiting components and may include current-limiting components Page 58 BS EN 61643-21:2001+A2:2013 64613-12 © CEI:2000 IEC 61643-21:2001+A2:2012 – 25 – t1 100 t2 96 % 95 % Relative humidity

Annex E (informative) Determination of let-through current (I p ) To determine the maximum let-through current I P at the output terminals of an SPD, the input terminals should be exposed to a specified test impulse selected from Table The output current waveform into a short-circuit (Figures E.1 to E.6) should be measured If the measured waveform is equal to the waveform given by Table 3, than the value I P is given by the peak value of the measured current Where the measured waveform deviates from the specified waveform according to Table 3, it can be assumed that at Figures 1b to 1f, the measured maximum current corresponds to I P At Figure 1a, I P is equal to the short-circuit current of the generator To get an exact calculation of coordination, it is necessary to use the let-through energy (LTE) method (see Clause F.5 of IEC 61643-12 or Clause C.4 of IEC 62305-4) This determination of the let-through current (I P ) is used to calculate a coordination of SPDs (see Figure E.1 in IEC 61643-22) If several test impulses are specified, the maximum values of U p and I P should be indicated for each test impulse Depending on the type of SPD (see 1.2), the test a), b) or c) should be chosen a) Asymmetrical application of test impulses to determine the differential mode I P (see Figure E.1) The test impulse is applied to the input side of the SPD b) Non-symmetrical application of test impulses to determine the common mode I P (see Figure E.2) The test impulse is applied to the input side of the SPD c) Symmetrical application of test impulses to determine the differential mode I P (see Figure E.3) The test impulse is applied by a current distributor (1:2) to the input side of the SPD d) Asymmetrical application of test impulses to determine the differential mode I P (see Figure E.4) The test impulse is applied to the input side of the SPD e) Symmetrical application of test impulses to determine the common mode I P (see Figure E.5) The test impulse is applied by a current distributor (1:2) to the input side of the SPD f) Symmetrical application of test impulses to determine the common mode I P (see Figure E.6) The test impulse is applied by a current distributor (1:n) to the input side of the SPD X1 G SPD (Figure 1a) IP A X2 IEC 558/08 NOTE The value of I P is equal to the surge current of the generator Figure E.1 – Determination of differential mode let-through current " Page 65 BS EN 61643-21:2001+A2:2013 IEC 61643-21:2001+A2:2012 !
