Live working - Voltage detectors - Part 3: Two-pole low-voltage type

This part of IEC 61243 is applicable to hand-held two-pole voltage detectors with its
accessories (crocodile clips and detachable leads) to be used in contact with parts of
electrical systems:

– for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2 3 Hz and up
to 500 Hz,
and/or
– for d.c. voltages not exceeding 1 500 V.

NOTE The a.c. voltages defined in this standard refer either to phase-to-phase voltages or phase to neutral voltages.

Contact electrode extensions are not covered by this standard.
Voltage detectors covered by this standard are intended to be used under dry and humid
conditions, both indoor and outdoor. They are not intended to be used under rain conditions.

Voltage detectors covered by this standard are not intended to be used for continuous
operation.

Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea
level.

This standard also includes provisions for the following supplementary functions when
available (see Annex B):
– phase indication,
– rotating field indication, and
– continuity check.

Other supplementary functions are not covered by this standard.

Voltage detectors covered by this standard are not considered as measuring devices.
Relevant safety requirements for measuring devices are included in IEC 61010 series.
