Live working - Portable equipment for earthing or earthing and short-circuiting

This International Standard is applicable to portable equipment, with or without matching connection points, for temporary earthing or earthing and short-circuiting of electrically isolated or de-energized a.c. and d.c. installations, distribution and transmission networks, whether they are overhead or underground or of low or high voltage. This standard covers equipment comprising an earthing or a short-circuiting or an earthing and short-circuiting device and insulating component. An example is given in Figure 1a and Figure 1b. It also covers: - earthing or short-circuiting or earthing and short-circuiting devices intended to be installed with insulating means. An example of an earthing device is given in Figure 1c; - separate components, such as conductive extension (see Figure 1b) or clamp or cable with end fittings. The performance of equipment, devices and components covered by this standard is based on electro-dynamic and electro-thermal effects acting during short-circuit. The withstand capability of the devices and equipment is expressed by their rated values of current, time and peak factor. No rated voltage is given, but the geometrical dimensions of the equipment are also linked to the voltage of the installation. Examples of connection diagrams of earthing and short-circuiting devices are given in Figures 2 and 3. Associated usual lengths of cables are given in Table 1. Not covered in this standard are: - insulating means, such as insulating sticks, telescopic sticks, insulating handles, insulating gloves, aerial devices with insulating booms, insulating ropes to be used to install the earthing and short-circuiting device; - insulating components, except for basic safety requirements for the insulating element; - devices meant only for the draining of induced currents; - relevant working procedures for using portable equipment for earthing or earthing and short-circuiting.

Arbeiten unter Spannung - Ortsveränderliche Geräte zum Erden oder Erden und Kurzschließen

Travaux sous tension - Equipements portables de mise à la terre ou de mise à la terre et en court-circuit

La CEI 61230:2008 est applicable aux équipements portables avec ou sans points de connexion assortis, pour mise temporaire à la terre ou mise à la terre et en court-circuit des installations électriques à courant alternatif ou à courant continu, isolées ou hors tension, des réseaux de distribution et de transport, qu'ils soient aériens ou souterrains et de tension basse ou haute. La présente norme couvre l'équipement comprenant un dispositif de mise à la terre ou de court-circuit, ou de mise à la terre et en court-circuit, et un composant isolant. La performance des équipements, dispositifs et composants couverts par la présente norme, est basée sur les effets électrodynamiques et électrothermiques mis en jeu durant le court-circuit. La capacité de tenue des équipements et dispositifs est exprimée par leurs valeurs assignées de courant, de temps et de facteur de crête. Aucune tension assignée n'est donnée mais les dimensions géométriques de l'équipement sont liées à la tension de l'installation. La seconde édition annule et remplace la première édition publiée en 1993. Cette édition constitue une révision technique. Les principaux changements sont:  - l'extension du domaine d'application pour couvrir l'usage des équipements sur des installations à courant continu;  - l'extension de l'usage de l'aluminium à toutes les parties conductrices du dispositif;  - la possibilité d'utiliser la présente norme pour des composants séparés de ces équipements;  - la révision générale des exigences et des essais;  - la révision des annexes existantes;  - l'introduction d'une nouvelle Annexe D informative proposant un guide pour déterminer la valeur efficace équivalente d'un courant de court-circuit et d'une nouvelle Annexe F normative traitant de la classification des défauts.

PORTABLE EQUIPMENT FOR EARTHING OR
EARTHING AND SHORT-CIRCUITING
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 61230 has been prepared by IEC technical committee 78: Live

working.

This second edition cancels and replaces the first edition published in 1993. It constitutes a

technical revision.
The major changes are:
– extension of the scope to cover the use of equipment on d.c. installations;
– extension of the use of aluminium to all conductive parts of the device;

– extension of the application to silicone rubber cables made by the revision of TC 20

PORTABLE EQUIPMENT FOR EARTHING OR
EARTHING AND SHORT-CIRCUITING
1 Scope

This International Standard is applicable to portable equipment, with or without matching

connection points, for temporary earthing or earthing and short-circuiting of electrically

isolated or de-energized a.c. and d.c. installations, distribution and transmission networks,

whether they are overhead or underground or of low or high voltage.
NOTE Annex A provides guidance for application to railway systems.

This standard covers equipment comprising an earthing or a short-circuiting or an earthing

and short-circuiting device and insulating component. An example is given in Figure 1a and

Figure 1b.
It also covers:

– earthing or short-circuiting or earthing and short-circuiting devices intended to be installed

with insulating means. An example of an earthing device is given in Figure 1c;

– separate components, such as conductive extension (see Figure 1b) or clamp or cable

with end fittings.

The performance of equipment, devices and components covered by this standard is based

on electro-dynamic and electro-thermal effects acting during short-circuit. The withstand

capability of the devices and equipment is expressed by their rated values of current, time

and peak factor. No rated voltage is given, but the geometrical dimensions of the equipment

are also linked to the voltage of the installation.

Examples of connection diagrams of earthing and short-circuiting devices are given in

Figures 2 and 3. Associated usual lengths of cables are given in Table 1.
Not covered in this standard are:

– insulating means, such as insulating sticks, telescopic sticks, insulating handles,

insulating gloves, aerial devices with insulating booms, insulating ropes to be used to

install the earthing and short-circuiting device;

– insulating components, except for basic safety requirements for the insulating element;

NOTE Basic safety recommendations for earthing sticks are given in Annex B.
– devices meant only for the draining of induced currents;
