Live working. Voltage detectors -- Two-pole low-voltage type
This part of IECÂ 61243 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems:
for a.c. voltages not exceeding 1Â 000Â V at nominal frequencies between 16Â 2/3Â Hz and up to 500Â Hz,
and/or
for d.c. voltages not exceeding 1Â 500Â V.
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 2Â 000Â 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 IECÂ 61010 series.
