Live working - Voltage detectors - Part 1: Capacitive type to be used for voltages exceeding 1 kV a.c.

IEC 61243-1:2003+A1:2009 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and frequencies of 50 Hz and/or 60 Hz. This part applies only to voltage detectors of capacitive type used in contact with the part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard (see 4.4.1 for general design). The contents of the corrigendum of October 2005 have been included in this copy. This consolidated version consists of the second edition (2003) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.

Travaux sous tension - Détecteurs de tension - Partie 1: Type capacitif pour usage sur des tensions alternatives de plus de 1 kV

La CEI 61243-1:2003+A1:2009 est applicable aux détecteurs de tension portatifs avec ou sans alimentation incorporée pour utilisation sur des réseaux électriques de tensions alternatives de 1 kV à 765 kV et de fréquences de 50 Hz et/ou 60 Hz. Cette partie s'applique uniquement aux détecteurs de tension de type capacitif utilisés en contact avec le composant à vérifier, en dispositif complet, élément isolant compris, ou en dispositif séparé adaptable sur une perche isolante qui, étant un outil séparé, n'est pas couverte par la présente norme (voir 4.4.1 pour la conception générale). Le contenu du corrigendum d'octobre 2005 a été pris en considération dans cet exemplaire.  Cette version consolidée comprend la deuxième édition (2003) et son amendement 1 (2009). Il n'est donc pas nécessaire de commander l'amendement avec cette publication.

LIVE WORKING – VOLTAGE DETECTORS –
Part 1: Capacitive type to be used for voltages
exceeding 1 kV a.c.
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 61243-1 has been prepared by IEC technical committee 78: Live

working.

This edition includes the following major technical changes from the previous edition:

a) the Scope has been extended to cover the use on electrical systems for voltages up to

765 kV a.c.;

b) the notion of family of voltage detectors which are identical in terms of design and

dimensions and only differ by their nominal voltages (or nominal voltage ranges) has been

included;

c) the classification in terms of the setting of the threshold voltage to give a clear indication

has been eliminated;

d) a new test set-up with bars has been introduced. Depending on the nominal voltage of the

voltage detector, it is required or becomes an alternative test set-up for checking the

influence of interference fields, the influence of interference voltages, the protection

against bridging and the spark resistance;
---------------------- Page: 6 ----------------------
61243-1 © IEC:2003+A1:2009 – 5 –
e) the revision of specific dielectric tests has been included;

f) some test procedures (clear perceptibility of audible indication, drop resistance, climatic

dependence) have been improved and completed.

This consolidated version of IEC 61243-1 consists of the second edition (2003) [documents

78/527/FDIS and 78/537/RVD], its amendment 1 (2009) [documents 78/751/CDV and
78/794/RVC] and its corrigendum of October 2005.

The technical content is therefore identical to the base edition and its amendment and has

been prepared for user convenience.
It bears the edition number 2.1.

A vertical line in the margin shows where the base publication has been modified by

amendment 1.

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

IEC 61243 consists of the following parts, under the general title Live working – Voltage

detectors:
Part 1: Capacitive type to be used for voltages exceeding 1 kV a.c.
Part 2: Resistive type to be used for voltages of 1 kV to 36 kV a.c.
Part 3: Two-pole low-voltage type
Part 5: Voltage detecting systems (VDS)

The committee has decided that the contents of the base publication and its amendments 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.

LIVE WORKING – VOLTAGE DETECTORS –
Part 1: Capacitive type to be used for voltages
exceeding 1 kV a.c.
1 Scope

This part of IEC 61243 is applicable to portable voltage detectors, with or without built-in

power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and

frequencies of 50 Hz and/or 60 Hz.

This part applies only to voltage detectors of capacitive type used in contact with the part to

be tested, as a complete device including its insulating element or as a separate device,

adaptable to an insulating stick which, as a separate tool, is not covered by this standard

(see 4.4.1 for general design).
Other types of voltage detectors are not covered by this part of the standard.

Some restrictions on their use are applicable in the case of factory-assembled switchgear and

on overhead systems of electrified railways (see Annex B, instructions for use).

NOTE Except where otherwise specified, all the voltages defined in this standard refer to values of phase-to-

phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth

(ground) voltages should be used to determine the operating voltage.

contact electrode

bare conductive part of the conductive element which establishes the electric connection to

the component to be tested
[IEV 651-10-09]
3.6
contact electrode extension

externally insulated conductive element between the indicator and the contact electrode,

intended to achieve the correct position of the indicator relative to the installation being tested

3.7
indicator

part of the voltage detector which indicates the presence or absence of the operating voltage

at the contact electrode
[IEV 651-10-08, modified]
3.8
adaptor

part of a voltage detector as a separate device which permits attachment of an insulating stick

3.9
insulating element

part of a voltage detector as a complete device that provides adequate safety distance and

insulation to the user

device in order to provide the length to reach the installation to be tested and adequate safety distance and

insulation to the user.
3.11
limit mark

distinctive location or mark to indicate to the user the physical limit to which the voltage

detector may be inserted between live parts or may touch them
3.12
hand guard
distinctive physical guard separating the handle from the insulating element

NOTE Its purpose is to prevent the hands from slipping and passing into contact with the insulating element.

3.13
testing element

built-in or external device, by means of which the functioning of the voltage detector can be

checked by the user
[IEV 651-10-11, modified]
3.14
accessories

items used to lengthen the handle or the contact electrode, to improve the efficiency of the

contact electrode or to enable the contact electrode to reach the part to be tested

---------------------- Page: 11 ----------------------
– 10 – 61243-1 © IEC:2003+A1:2009
3.15
nominal voltage
suitable approximate value of voltage used to identify a system or device
[IEV 601-01-21, modified]

NOTE The nominal voltage of the voltage detector is the parameter associated with its clear indication. A voltage

detector may have more than one nominal voltage, or a nominal voltage range. Limit values of the nominal voltage

range are named U min and U max.
n n
3.16
operating voltage (in a system)

value of the voltage under normal conditions, at a given instant and a given point of the

system
NOTE This value may be expected, estimated or measured.
[IEV 601-01-22]
3.17
threshold voltage

minimum voltage between the live part and earth (ground) required to give a clear indication

corresponding to specific conditions as defined in the corresponding test

NOTE As defined in this part of IEC 61243, threshold voltage is related to specific test conditions. Users should be

aware that their requirements for threshold voltage for field operation need to be related to the test conditions in

the standard.
3.18
rated voltage

value of voltage generally agreed upon by manufacturer and customer, to which certain

operating specifications are referred. The rated voltage of the voltage detector is the voltage

selected from IEC 60071-1, Tables 2 and 3, column 1, which should either be equal to the

nominal voltage (or the highest nominal voltage of its nominal voltage range), or the next

higher voltage selected from those tables
3.19
interference voltage
voltage picked up inductively or capacitively by the part to be tested
3.20
interference field

superposed electric field which may affect the indication. It may result from the part to be

tested or other adjacent parts, and may have any phase relationship
NOTE The extreme cases for the tests are:

– an in-phase interference field exists when a small change of potential in the direction of the voltage detector

axis results in an incorrect indication. This occurs as a result of the dimensions and/or configuration of the part

of installation to be tested (or of adjacent parts of the installation having voltages in the same phase);

– an interference field in phase opposition exists when a strong change of potential
