Measuring relays and protection equipment - Part 11: Voltage dips, short interruptions, variations and ripple on auxiliary power supply port

IEC 60255-11:2008 specifies the general requirements for a.c. and d.c. power supplies, 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 energised and subjected to dips, interruptions and alternating components (ripple). The main differences with respect to the previous edition are as follows: addition of voltage dips and interruptions test in a.c.; addition of gradual shut-down/start-up test; addition of reversal of d.c. power supply polarity test.

Relais de mesure et dispositifs de protection - Partie 11: Creux de tension, coupures brèves, variations et ondulation sur l'accès alimentation auxiliaire

La CEI 60255-11:2008 spécifie les prescriptions générales pour les alimentations auxiliaires en courant continu et en courant alternatif, pour les relais de mesure et les dispositifs de protection des systèmes de protection, y compris les équipements de contrôle, de supervision et d'interface avec le processus utilisés avec ces systèmes. L'objectif de ces essais est de confirmer que le matériel sous test fonctionnera correctement lorsqu'il sera alimenté et soumis à des creux, des coupures et des composantes alternatives (ondulations) de tension. Les principales différences par rapport à l'édition précédente sont les suivantes: ajout essais creux et coupures en c.a.; ajout essais coupure rétablissement progressifs; ajout essais inversion de polarité en c.c.

Merilni releji in zaščitna oprema - 11. del: Napetostni upadi, kratke prekinitve, spremembe napetosti in valovitosti na vhodu za pomožno napajanje

Ta del serije IEC 60255 določa splošne zahteve za napajalnike z enosmernim ali izmeničnim tokom za merilne releje in zaščitno opremo za zaščito napajalnih sistemov, vključno z opremo za nadzor, spremljanje in vmesniško procesno opremo, ki se uporablja s temi sistemi. Ta del temelji na: - IEC 61000-4-11 za upade napetosti izmeničnega toka, kratke prekinitve in spremembe napetosti; - IEC 61000-4-17 za valovanja napetosti; - IEC 61000-4-29 za upade napetosti enosmernega toka, kratke prekinitve in spremembe napetosti. Cilj preskusov je potrditi, da bo preskušana oprema ob dovajanju elektrike in ob izpostavljenosti upadom, prekinitvam in izmeničnim komponentam (valovanju) delovala pravilno. 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 navesti: - definicije uporabljenih izrazov; - stopnje natančnosti preskusa; - preskusno opremo; - postavitev preskusa; - preskusni postopek; - merila sprejemljivosti; - poročilo o preskusu.

MEASURING RELAYS AND PROTECTION EQUIPMENT –

Part 11: Voltage dips, short interruptions, variations

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 60255-11 has been prepared by IEC technical committee 95:
Measuring relays and protection equipment.
This second edition cancels and replaces the first edition published in 1979. This edition
constitutes a technical revision. The main differences with respect to the previous edition
concern:
• addition of voltage dips and interruptions test in a.c.;
• addition of gradual shut-down/start-up test;
• addition of reversal of d.c. power supply polarity test.
