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

IEC 61243-1:2021 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 800 kV AC, and frequencies of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare 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 document (see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B) and systems without neutral reference. For systems without neutral reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document contribute to the safety of users provided they are used by persons trained for the work, in accordance with the hot stick working method and the instructions for use.
Except where otherwise specified, all the voltages defined in this document 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 are used to determine the operating voltage.
This third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage.
b) A contact probe is introduced as a new type of non-conductive contact electrode.
c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure.
d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded.
e) The marking for voltage detectors with low interference voltage has been made more precise.
f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added.
g) Requirements and tests for electromagnetic compatability have been implemented.
h) An example for good electrical connection for the tests is introduced.

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

IEC 61243-1:2021 s’applique aux détecteurs de tension portatifs, avec ou sans sources d’énergie intégrées, à utiliser sur les systèmes électriques pour des tensions de 1 kV à 800 kV AC, et des fréquences de 50 Hz et/ou 60 Hz.
Ce document ne s’applique qu’aux détecteurs de tension de type capacitif utilisés au contact de la partie nue à tester, en tant qu’appareil complet comprenant son élément isolant ou en tant qu’appareil séparé, adaptable à un bâton isolant qui, en tant qu’outil distinct, n’est pas couvert par ce document (voir 4.4.2.1 pour la conception générale).
D’autres types de détecteurs de tension ne sont pas couverts par ce document.
Les détecteurs de tension auto-allant (formellement « détecteurs de tension multi-portée ») ne sont pas couverts par ce document.
Certaines restrictions ou interdictions formelles de leur utilisation s’appliquent en cas de commutateur de conception de la série IEC 62271, en raison de la coordination de l’isolation, sur les systèmes de lignes aériennes des chemins de fer électrifiés (voir annexe B) et les systèmes sans référence neutre. Pour les systèmes sans référence neutre, le niveau isolant est adapté à la tension maximale possible à la terre (sol).
Les produits conçus et fabriqués selon ce document contribuent à la sécurité des utilisateurs à condition qu’ils soient utilisés par des personnes formées pour le travail, conformément à la méthode de travail hot stick et aux instructions d’utilisation.
Sauf indication contraire, toutes les tensions définies dans ce document se réfèrent aux valeurs des tensions de phase en phase des systèmes en trois phases. Dans d’autres systèmes, les tensions de phase en phase ou de phase à terre (sol) applicables sont utilisées pour déterminer la tension de fonctionnement.
Cette troisième édition annule et remplace la deuxième édition publiée en 2003 et Amend-ment 1:2009. Cette édition constitue une révision technique.
Cette édition comprend les changements techniques importants suivants par rapport à l’édition précédente :
a) La portée est plus précise, indiquant que seul le contact nu avec la pièce à tester est fiable pour ces détecteurs de tension de contact. La raison en est que les essais sur les conducteurs peints ou enduits ont donné lieu à de mauvaises indications, car cette peinture ou ce manteau non conducteur agit comme un condensateur avec une capacité différente selon l’épaisseur. Cette capacité a un effet sur la tension du seuil.
b) Une sonde de contact est introduite comme un nouveau type d’électrode de contact non conductrice.
c) Un nouveau type « type exclusivement extérieur » a été défini et mis en œuvre dans les exigences et la procédure d’essai.
d) Un sélecteur de tension et de fréquence est autorisé si une mauvaise utilisation prévisible est exclue.
e) Le marquage des détecteurs de tension à basse tension a été rendu plus précis.
f) Les groupes d’indication ont été rendus plus précis et les exigences et les tests pour l'«état prêt à fonctionner » et « état de stand-by » ajouté.
g) Des exigences et des tests de compatibilité électromagnétique ont été mis en œuvre.
h) Un exemple de bonne connexion électrique pour les tests est introduit.

Overview

IEC 61243-1:2021 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for live working voltage detectors of the capacitive type. These portable voltage detectors are designed for use on electrical systems with alternating current (AC) voltages exceeding 1 kV, specifically from 1 kV up to 800 kV AC at frequencies of 50 Hz and 60 Hz. The standard focuses exclusively on capacitive voltage detectors used in direct contact with bare conductive parts to ensure accurate detection of voltage presence.

This third edition replaces the 2003 edition and 2009 amendment, reflecting technical revisions that enhance clarity, reliability, and safety. It includes updated provisions related to design, functionality, electromagnetic compatibility, and more, to better support safe live working practices.

Key Topics

  • Scope and Application
    The standard applies only to capacitive voltage detectors that contact bare conductive parts directly or are adaptable as complete devices including insulating elements. It excludes multi-range (self-ranging) detectors and other types of voltage detectors.

  • Design and Construction Requirements
    Requirements cover mechanical strength, insulating materials, grip force, vibration and shock resistance, and protection against sparking or bridging faults. The standard introduces a new "contact probe" type and defines an "exclusively outdoor type" with tailored specifications.

  • Functional Performance
    Clear and perceptible indication systems (visual and audible), response times, frequency and temperature dependencies, and power source dependability are specified to ensure reliable live voltage detection.

  • Electromagnetic Compatibility (EMC)
    New EMC requirements and testing procedures ensure voltage detectors perform reliably in environments with electromagnetic interference.

  • Marking and User Documentation
    Clear markings for voltage levels, low interference voltage, and usage instructions are mandated to promote safe handling and user awareness. Instructions include guidelines on the correct use of selectors and precautions against foreseeable misuse.

  • Testing Procedures
    Comprehensive testing covers dielectric strength, leakage current, functional verification, mechanical durability, climatic conditions, and misuse scenarios to verify compliance and operational safety.

  • Safety Considerations
    The standard emphasizes that devices meeting its requirements enhance user safety only when used by trained personnel following established hot stick live working techniques and documented instructions.

Applications

IEC 61243-1:2021 voltage detectors are critical tools for electrical engineers, field technicians, and maintenance workers involved in live working on medium to high-voltage AC electrical systems such as:

  • High voltage overhead transmission lines (up to 800 kV AC)
  • Substation equipment and switchgear compliant with IEC 62271 series
  • Electrical distribution networks requiring verification of voltage presence before or during maintenance
  • Electrified railway systems with overhead lines, taking into account insulation design and neutral reference conditions

The standard supports safety by standardizing reliable detection devices used to prevent accidental contact with live conductors and reduce electrical hazards during live working operations.

Related Standards

  • IEC 62271 series – High-voltage switchgear and controlgear requirements, referenced for insulation coordination and usage restrictions with voltage detectors.
  • IEC 60417-5216 – Symbol for suitability in live working, referenced for marking voltage detectors approved for such use.
  • Other IEC standards covering electrotechnical safety measures, insulating tools, portable electrical test instruments, and electromagnetic compatibility.

Summary

IEC 61243-1:2021 plays a vital role in ensuring the safety and reliability of capacitive voltage detectors used on AC electrical systems above 1 kV. By setting rigorous design, performance, marking, and testing requirements, this standard underpins safe live working practices to protect personnel from electrical hazards. Its implementation enables manufacturers and users to adhere to globally recognized safety benchmarks, promote operational consistency, and mitigate risks associated with voltage detection in high-voltage environments.

Part 1: Capacitive type to be used for voltages
exceeding 1 kV AC
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 prepa-
ration 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 Stand-
ardization (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 inter-
ested 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 misinter-
pretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications trans-
parently 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 ex-
penses 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 third edition cancels and replaces the second edition published in 2003 and Amend-
ment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The scope is more precise, stating that only bare contact to the part to be tested is reliable
for these contact voltage detectors. The rationale is that tests on painted or coated
conductors have led to wrong indications, as this non-conductive paint or coat acts as a
capacitor with different capacity according to the thickness. This capacity has an effect on
the threshold voltage.
b) A contact probe is introduced as a new type of non-conductive contact electrode.
c) A new type "exclusively outdoor type" has been defined and implemented into the
requirements and test procedure.

d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded.
e) The marking for voltage detectors with low interference voltage has been made more
precise.
f) The indication groups have been made more precise and requirements and tests for the
"ready to operate state" and "stand-by state" added.
g) Requirements and tests for electromagnetic compatability have been implemented.
h) An example for good electrical connection for the tests is introduced.
i) A new test set-up with one bar has been added for voltage detectors of category L for
overhead line configuration.
j) A dielectric test for tubes and rods has been implemented for those not covered by
IEC 60855-1 or IEC 61235.
k) Old Annex E (mechanical shock test – pendulum method) has been deleted
(see IEC 60068-2-75 pendulum method) and replaced by an information and a guideline on
the use of the limit mark and the contact electrode extension.
l) Annex E and Annex F have swapped places to make it easier for the reader to combine the
classification of defects (Annex D) and the rationale for this classification (new Annex E).
m) A new informative Annex H has been created to give information for further developments
of voltage detectors due to field experiences.
n) Editorial changes have been made to harmonize with other new published standards.
The text of this International Standard is based on the following documents:

INTRODUCTION
This document has been prepared according to the requirements of IEC 61477, where
applicable.
LIVE WORKING – VOLTAGE DETECTORS –

Part 1: Capacitive type to be used for voltages
exceeding 1 kV AC
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 800 kV AC, and frequencies
of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare
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 document
(see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
NOTE Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of
IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified
railways (see Annex B) and systems without neutral reference. For systems without neutral
reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document contribute to the safety of
users provided they are used by persons trained for the work, in accordance with the hot stick
working method and the instructions for use.
Except where otherwise specified, all the voltages defined in this document 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 are used to determine the operating voltage.

IEC 61243-1:2021 is a standard for portable voltage detectors used on electrical systems with voltages ranging from 1 kV to 800 kV AC and frequencies of 50 Hz and/or 60 Hz. The standard specifically applies to capacitive type voltage detectors that are used in contact with the bare part being tested. It does not cover other types of voltage detectors or self-ranging voltage detectors. There are restrictions on the use of these detectors in certain situations, such as switchgear of IEC 62271 series design, overhead line systems of electrified railways, and systems without a neutral reference. The document emphasizes that the detectors must be used by trained individuals following the hot stick working method and the provided instructions. This edition of the standard includes several technical changes, including a more specific scope, the addition of a contact probe as a non-conductive contact electrode, a new category for exclusively outdoor use, allowance for a selector for voltage and frequency, more precise marking for voltage detectors with low interference voltage, more specific indication groups, requirements and tests for the "ready to operate state" and "stand-by state", implementation of requirements and tests for electromagnetic compatibility, and the introduction of an example for good electrical connection during testing. This edition replaces the previous edition published in 2003 and its amendment.

記事タイトル:IEC 61243-1:2021−ライブワーキング−電圧検出器−パート1:1 kV ACを超える電圧に使用される容量タイプ 記事内容:IEC 61243-1:2021は、バッテリー内蔵の有無に関わらず、1 kVから800 kV ACの電圧および50 Hzおよび/または60 Hzの周波数を持つ電気システムで使用される携帯用電圧検出器に適用される。本書は、被検査対象の露出部分と接触する容量タイプの電圧検出器にのみ適用され、絶縁素子を含む完全なデバイスとして、または別のデバイスとして使用される、絶縁スティックに適応できる別のデバイスとして使用される。本書は絶縁スティックとして使用される別のツールには適用されない(一般設計については4.4.2.1を参照)。 本書は他のタイプの電圧検出器には適用されない。 セルフレンジング電圧検出器(旧称 “マルチレンジ電圧検出器”)は本書には含まれていない。 IEC 62271シリーズのスイッチギア、電化鉄道の架線システム(付属書Bを参照)および中性を参照しないシステムの場合、絶縁調整により、その使用に制限または正式な禁止が適用される。中性を参照しないシステムの場合、絶縁レベルは地面に対する最大可能な電圧に適応される。 本書に準拠して設計および製造された製品は、適切な作業者によってホットスティック作業法および使用説明書に従って使用される限り、ユーザーの安全性に寄与する。 それ以外の場合、本文書で定義されたすべての電圧は、三相システムの相間電圧の値を指す。他のシステムでは、適用される相間または相対地(グラウンド)電圧が動作電圧を決定するために使用される。 本版は、2003年に発行された第2版および改訂版1:2009を取り消し、置き換える。この版は技術的な改訂を行ったものである。 この版には、以下の重要な技術的な変更が含まれている: a)範囲がより具体的であり、これらの接触電圧検出器に信頼性のあるものは被検査対象の露出部分との接触だけであると述べている。これは、塗装またはコーティングされた導体のテストでは誤った表示が行われることがあるためであり、非導電性のペイントまたはコートが異なる容量を持つコンデンサの役割を果たすためである。この容量はしきい値電圧に影響を与える。 b)非導電性の接触プローブが新しいタイプとして導入されている。 c)「専用の屋外タイプ」が定義され、要件およびテスト手順に組み込まれている。 d)予測される誤用が除外されている場合、電圧および周波数セレクタが許可される。 e)干渉電圧の低い電圧検出器のマーキングがより具体的になっている。 f)指示グループをより具体化し、「動作可能状態」と「スタンバイ状態」の要件およびテストを追加した。 g)電磁環境適合性の要件およびテストが実装されている。 h)テストのための良好な電気接続の例が導入されている。

제목: IEC 61243-1:2021 - 작업 전원 - 전압 감지기 - 파트 1: 1 kV AC를 초과하는 전압에 사용되는 커패시터 타입 내용: IEC 61243-1:2021은 내장된 전원이 있는지 여부와 관계없이 1 kV에서 800 kV AC의 전압 및 50 Hz와/또는 60 Hz의 주파수를 가진 전기 시스템에 사용되는 휴대용 전압 감지기에 적용됩니다. 이 문서는 테스트하려는 눈에 보이는 부분과 함께 사용되는 커패시터 유형의 전압 감지기에만 적용되며, 단일 기기로 사용되는 단위로써 또는 별도의 도구로 사용되는 단위로 사용됩니다. 별도의 도구로 사용되는 절연봉은 이 문서에 포함되지 않습니다(일반 설계에 대한 4.4.2.1을 참조하십시오). 이 문서는 다른 유형의 전압 감지기에는 적용되지 않습니다. Self ranging voltage detectors(정식으로는 "multi range voltage detectors")는 이 문서에는 해당되지 않습니다. 기존 설계(IEC 62271 시리즈)의 스위치기어, 전동 철도의 공중선 시스템(부록 B 참조) 및 중립접지 시스템의 경우 사용 제약이나 공식적인 금지가 적용됩니다. 중립접지시스템의 경우, 절연수준은 가능한 최대 전압에 대해 대응되도록 조정됩니다. 이 문서에 따라 설계되고 제조된 제품은 교육받은 작업자에 의해 핫스틱 작업 방법과 사용 설명서에 따라 사용될 경우 사용자의 안전성에 기여합니다. 그 외 특별히 명시되지 않는 한,이 문서에서 정의 된 모든 전압은 삼상 시스템의 상간 전압 값에 대한 값으로 참조됩니다. 다른 시스템의 경우, 적용 가능한 상간 상 또는 상대 지지(지면) 전압은 작동 전압을 결정하는 데 사용됩니다. 이번 판은 2003년에 발표 된 2판 및 1개 판 변경 사항을 대체합니다. 이번 판은 기술적인 개정을 포함합니다. 이번 판은 이전 버전과 비교하여 다음과 같은 중요한 기술적인 변경 사항을 포함합니다: a) 범위가 더 정확하게 명시되어 이 접촉 전압 감지기들은 눈에 보이는 부분에만 유효하다고 명시됩니다. 그러나 커패시터 유형 전압 감지기는 페인트 또는 코팅된 도체를 테스트하는 경우 잘못된 표시를 유발할 수 있다는 이유로 이 문서에는 해당되지 않습니다. 페인트나 코팅은 두께에 따라 용량이 다른 커패시터 역할을 하기 때문에 이러한 영향이 경계 전압에 영향을 미칩니다. b) 비도체 접촉 전극으로 새로운 유형의 접촉 프로브가 도입되었습니다. c) '외부 전용 타입'이라는 새로운 유형이 정의되어 요구사항 및 테스트 절차에 구현되었습니다. d) 예상 시 오용이 배제된 경우에는 전압 및 주파수 선택기가 허용됩니다. e) 간섭 전압이 낮은 전압 감지기에 대한 표시가 보다 정확하게 되었습니다. f) 표시 그룹이 더 정확하게되었으며, '운용 준비 상태' 및 '대기 상태'에 대한 요구 사항과 테스트가 추가되었습니다. g) 전자기적 호환성에 대한 요구사항과 테스트가 구현되었습니다. h) 테스트를 위한 좋은 전기 연결의 예제가 도입되었습니다.
