IEC 61243-3-2014 带电作业--验电器--第3部分：两极低压型 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 their 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.dition 3.0 2014-10 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Live working – Voltage detectors – Part 3: Two-pole low-voltage type Travaux sous tension – Détecteurs de tension – Partie 3: Type bipolaire basse tension IEC 61243-3:2014-10(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2014 IEC, Geneva, Switzerland All rights reserved.
