Measuring relays and protection equipment - Part 22-5: Electrical disturbance tests - Surge immunity test
IEC 60255-22-5:2008 specifies the general requirements for surge immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems. Is based on IEC 61000-4-5. The objective of the tests is to confirm that the equipment under test will operate correctly when energized and subjected to high-energy disturbances on the power and interconnection lines, caused by surge voltages from switching and lightning effects. The main change in this new edition concerns line to earth tests.

Relais de mesure et dispositifs de protection - Partie 22-5: Essais d'influence électrique - Essais d'immunité aux ondes de choc
La CEI 60255-22-5:2008 spécifie les exigences générales pour les essais d'immunité aux ondes de choc des relais de mesure et dispositifs de protection des systèmes de protection, en prenant en compte les interfaces avec le processus ainsi que les interfaces de commande et de surveillance utilisés avec ces systèmes. Est basée sur la CEI 61000-4-5. Le but de ces essais est d'obtenir la confirmation que l'équipement à l'essai fonctionnera correctement lorsqu'il sera alimenté et soumis à des perturbations hautement énergétiques sur les lignes d'alimentation et d'interconnexion, causées par des surtensions dues à des commutations et à la foudre. Le principal changement de cette nouvelle édition concerne les tests en mode commun.
Merilni releji in zaščitna oprema - 22-5. del: Preskusi električnih motenj - Preskus odpornosti proti napetostnemu udaru
Ta del serije IEC 60255 temelji na IEC 61000-4-5 in se na to objavo nanaša, kjer je ustrezno, in določa splošne zahteve za preskuse odpornosti proti napetostnemu udaru za merilne releje in zaščitno opremo za zaščito napajalnih sistemov, vključno s krmilno, nadzorno in procesno vmesniško opremo, ki se uporablja s temi sistemi.
Cilj preskusov je potrditi, da bo preskušana oprema ob dovajanju elektrike in ob izpostavljenosti visokoenergetskim motnjam napajalnih in povezovalnih vodov, ki jih povzročajo prenapetosti zaradi preklopov in delovanja strele, delovala pravilno.
Ta standard ni namenjen preskušanju zmožnosti izolacije, da zdrži visokonapetostno obremenitev. Preskus izolacije zajema IEC 60255-27.
Zahteve, ki jih določa ta standard, veljajo za nove merilne releje in zaščitno opremo; vsi navedeni preskusi pa so le tipski preskusi.
Namen tega standarda je opredeliti:
• uporabljene izraze,
• stopnje natančnosti preskusa,
• preskusno opremo,
• postavitev preskusa,
• preskusne postopke,
• merila sprejemljivosti,
• zahteve za poročilo o preskusu.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60255-22-5 has been prepared by technical committee 95: Measuring relays and protection equipment. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The main change concerns line to earth tests (see Figures 8, 9, 10). The text of this standard is based on the following documents: FDIS Report on voting 95/242/FDIS 95/247/RVD
Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. SIST EN 60255-22-5:2011

Surge immunity test
1 Scope and object This part of IEC 60255 is based on IEC 61000-4-5, referring to that publication where applicable, and specifies the general requirements for surge immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems. The objective of the tests is to confirm that the equipment under test will operate correctly when energized and subjected to high-energy disturbances on the power and interconnection lines, caused by surge voltages from switching and lightning effects. This standard does not intend to test the capability of the insulation to withstand high-voltage stress. The insulation test is covered by IEC 60255-27. The requirements specified in this standard are applicable to measuring relays and protection equipment in a new condition and all tests specified are type tests only. The object of this standard is to define: • terms used; • test severity levels; • test equipment; • test set-up; • test procedures; • criteria for acceptance; • test report requirements. 2 Normative references The fo
