High-voltage switchgear and controlgear - Part 213: Voltage detecting and indicating system (IEC 62271-213:2021)

This part of IEC 62271 is applicable to the voltage detecting and indicating system (VDIS) to
be installed on indoor and outdoor high-voltage equipment.
The VDIS as defined by this document includes a coupling system per phase (capacitive,
resistive coupling or other technology) to connect to live parts (main circuit).
The VDIS is applicable on systems with nominal voltages above 1 kV and service frequencies
from 16,7 Hz up to and including 60 Hz. The VDIS is used to detect and indicate the presence
or absence of operating voltage. It is not intended to distinguish between voltage not present
(i.e. U < 10 % of nominal voltage) and dead circuit state (i.e. U = 0 V).
NOTE 1 The use of a specific means of connection to earth of the main circuit (e.g. by an earthing switch) provides
the "dead circuit" (U = 0 V) state.
NOTE 2 The VDIS has the same threshold values as the voltage presence indicating system (VPIS) (IEC 62271-
206) and the voltage detecting system (VDS) (IEC 61243-5) for not indicating presence of voltage and for detecting
an absence of operating voltage, respectively.
The VDIS is fixed on equipment such as switchgear and controlgear according to the IEC 62271
series or transformers according to their own standards.
The products designed and manufactured in accordance with this document contribute to the
safety of the users, provided they are used by skilled or instructed persons in accordance with
safe methods of work and the instructions for use.

Appareillage à haute tension - Partie 213: Système détecteur et indicateur de tension (IEC 62271-213:2021)

L’IEC 62271-213:2021 s’applique au système détecteur et indicateur de tension (VDIS) à installer sur des équipements haute tension pour installation à l’intérieur et à l’extérieur. Le VDIS défini par le présent document comprend un système de couplage par phase (couplage capacitif, résistif ou d’une autre technologie) assurant la connexion avec les parties actives (circuit principal). Cette première édition annule et remplace la première édition de l’IEC 61243-5 parue en 1997 et la première édition de l’IEC 62271-206 parue en 2011. Cette édition est issue de la fusion de l’IEC 61243-5 et de l’IEC 62271-206. Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes de l’IEC 61243-5 et l’IEC 62271-206: a) un signal de sortie facultatif est défini pour être utilisé dans les cas d’utilisation générale; b) une seule interface est définie pour le système détecteur et indicateur de tension (VDIS); c) le mesurage de la capacité de courant admissible dans le dispositif limiteur de tension est considéré comme étant inexact et n’est pas traité dans le présent document. L’expérience démontre que la probabilité d’une défaillance de l’élément de couplage est négligeable.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 213: Voltage detecting and indicating system
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 62271-213 has been prepared by subcommittee 17C:Assemblies,

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

This first edition cancels and replaces the first edition of IEC 61243-5 published in1997 and the

first edition of IEC 62271-206 published in 2011. This edition constitutes a merging of the

content of IEC 61243-5 and IEC 62271-206.

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

editions of IEC 61243-5 and IEC 62271-206:
a) an optional output signal is defined to be used for multipurpose use cases;

b) only one interface is defined for voltage detecting and indicating system (VDIS);

c) the measurement of the current carrying capacity of the voltage limiting element is

considered as inaccurate and is not considered in this document. Experience shows that

the probability of failure of the coupling element is negligible.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 213: Voltage detecting and indicating system
1 Scope

This part of IEC 62271 is applicable to the voltage detecting and indicating system (VDIS) to

be installed on indoor and outdoor high-voltage equipment.

The VDIS as defined by this document includes a coupling system per phase (capacitive,

resistive coupling or other technology) to connect to live parts (main circuit).

The VDIS is applicable on systems with nominal voltages above 1 kV and service frequencies

from 16,7 Hz up to and including 60 Hz. The VDIS is used to detect and indicate the presence

or absence of operating voltage. It is not intended to distinguish between voltage not present

(i.e. U < 10 % of nominal voltage) and dead circuit state (i.e. U = 0 V).

NOTE 1 The use of a specific means of connection to earth of the main circuit (e.g. by an earthing switch) provides

the "dead circuit" (U = 0 V) state.

NOTE 2 The VDIS has the same threshold values as the voltage presence indicating system (VPIS) (IEC 62271-

206) and the voltage detecting system (VDS) (IEC 61243-5) for not indicating presence of voltage and for detecting

an absence of operating voltage, respectively.

The VDIS is fixed on equipment such as switchgear and controlgear according to the IEC 62271

series or transformers according to their own standards.

The products designed and manufactured in accordance with this document contribute to the

safety of the users, provided they are used by skilled or instructed persons in accordance with

safe methods of work and the instructions for use.
