Metallic cables and other passive components - Test methods - Part 4-17: Electromagnetic compatibility (EMC) - Reduction Factor

IEC 62153-4-17:2018 applies to the testing of the reduction factor of multi-element metallic cables used in analogue and digital communication and control. The described method is generally applicable to all screened metallic cables.
The reduction factor describes the screening effectiveness of a cable screen at frequencies below 1 kHz with a ratio of voltages describing the screened and unscreened situation. During the measurement, the cable under test is connected to a specific current loop arrangement.

Câbles métalliques et autres composants passifs - Méthodes d'essai - Partie 4-17: Compatibilité électromagnétique (CEM) - Facteur de réduction

L'IEC 62153-4-17:2018 s'applique aux essais sur le facteur de réduction de câbles métalliques à éléments multiples utilisés pour les communications et les commandes analogiques et numériques. La méthode décrite est généralement applicable à tous les câbles métalliques écrantés.
Le facteur de réduction décrit l'efficacité d'un écran de câble à des fréquences inférieures à 1 kHz par un rapport de tensions décrivant la situation écrantée et non écrantée. Pendant la mesure, le câble en essai est raccordé à une boucle de courant spécifique.

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 62153-4-17 has been prepared by technical committee 46: Cables,

Part 4-17: Electromagnetic compatibility (EMC) – Reduction Factor

1 Scope
Multi-element metallic communication and control cables are often designed with metallic
screen against harmful effects of electromagnetic fields e.g. generated in the environment of
electric power and electrified railway lines [1] .
This part of IEC 62153 applies to the testing of the reduction factor of multi-element metallic
cables used in analogue and digital communication and control. The described method is
generally applicable to all screened metallic cables.
The reduction factor describes the screening effectiveness of a cable screen at frequencies
below 1 kHz with a ratio of voltages describing the screened and unscreened situation. During
the measurement, the cable under test is connected to a specific current loop arrangement.
