High-voltage switchgear and controlgear - Part 104: Alternating current switches for rated voltages higher than 52 kV (IEC 62271-104:2020)

This part of IEC 62271 is applicable to three-pole alternating current switches for rated
voltages higher than 52 kV, having making and breaking current ratings, for indoor and
outdoor installations, and for rated frequencies up to and including 60 Hz.
This document is also applicable to the operating devices of these switches and to their
auxiliary equipment.
NOTE 1 Switches for gas insulated switchgear are covered by this document.
NOTE 2 Switches having a disconnecting function and called switch-disconnectors are also covered by
IEC 62271-102.
NOTE 3 Earthing switches are not covered by this document. Earthing switches forming an integral part of a
switch are covered by IEC 62271-102.
The main object of this document is to establish requirements for switches used in
transmission and distribution systems. General purpose switches for this application are
designed to comply with the following service applications:
– carrying rated continuous current;
– carrying short-circuit currents for a specified time;
– switching of mainly active loads;
– switching of no-load transformers;
– switching of the charging current of unloaded cables, overhead lines or busbars;
– switching of closed-loop circuits;
– making short-circuit currents.
A further object of this document is to establish requirements for limited purpose and special
purpose switches used in transmission and distribution systems.
Limited purpose switches comply with one or more of the service applications indicated above.
Special purpose switches may comply with one or more of the service applications indicated
above and, in addition, are suitable for one or more of the following applications:
– switching single capacitor banks;
– switching back-to-back capacitor banks;
– switching shunt reactors including secondary or tertiary reactors switched from the primary
side of the transformer;
– applications requiring an increased number of operating cycles;
– switching under earth fault conditions in non-effectively earthed neutral systems.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 104: Alternating current switches
for rated voltages higher than 52 kV
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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 62271-104 has been prepared by subcommittee 17A: Switching

devices, of IEC technical committee 17: High-voltage switchgear and controlgear.

This third edition replaces and cancels the second edition published in 2015. It constitutes a

technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
– new numbering, following IEC 62271-1:2017.

The text of this document is based on the following documents:
FDIS Report on voting
17A/1273/FDIS 17A/1278/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

This standard is to be read in conjunction with IEC 62271-1:2017, IEC 62271-100: ,

IEC 62271-102:2018 and IEC 62271-110:2017. In order to simplify the indication of

corresponding requirements, the same numbering of clauses and subclauses is used as in

IEC 62271-1. Modifications to these clauses and subclauses are given under the same

numbering, whilst additional subclauses are numbered from 101.

A list of all parts in the IEC 62271 series, published under the general title High-voltage

switchgear and controlgear, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
