Measuring relays and protection equipment - Part 22-3: Electrical disturbance tests - Radiated electromagnetic field immunity
Specifies the general requirements for radiated electromagnetic field 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 tests are intended to confirm that the equipment under test will operate correctly when energised and subjected to an electromagnetic field. The main change with respect to the previous edition concerns the extension of the frequency range.

MEASURING RELAYS AND PROTECTION EQUIPMENT –
Part 22-3: Electrical disturbance tests –
Radiated electromagnetic field immunity
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 60255-22-3 has been prepared by IEC technical committee 95:
Measuring relays and protection equipment.
This third edition cancels and replaces the second edition published in 2000. The main change
with respect to the previous edition concerns the extension of the frequency range to be tested.
The text of this standard is based on the following documents:
FDIS Report on voting
95/209/FDIS 95/215/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.
A list of all parts of IEC 60255 series, published under the general title Measuring relays and
protection equipment, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

MEASURING RELAYS AND PROTECTION EQUIPMENT –
Part 22-3: Electrical disturbance tests –
Radiated electromagnetic field immunity
1 Scope and object
This part of IEC 60255 is based on IEC 61000-4-3, referring to that publication where
applicable, and specifies the general requirements for radiated electromagnetic field 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 (EUT) will operate
correctly when energised and subjected to an electromagnetic field from a radiation source
operating within the frequency range 80 MHz to 2,7 GHz.
NOTE 1 The product standard IEC 60255-22-6 (based on IEC 61000-4-6) establishes the immunity of measuring
relays and protection equipment over the frequency range of 0,15 MHz to 80 MHz.
NOTE 2 The test methods defined in this standard are structured for the primary objective of establishing
adequate repeatability of results at various test facilities for qualitative analysis of effects. The test methods using a
portable transmitter are not taken into consideration here because the EMC directive now specifies a sweep test,
calibrated field strengths must be used and the portable transmitter test is not generally reproducible.
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.
