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-tophase
voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-toearth
(ground) voltages are used to determine the operating voltage.
