PD IEC/TR 61243-6:2017


This standard PD IEC/TR 61243-6:2017 Live working. Voltage detectors is classified in these ICS categories:
  • 29.240.99 Other equipment related to power transmission and distribution networks
  • 29.260.99 Other electrical equipment for working in special conditions
  • 29.240.20 Power transmission and distribution lines
  • 13.260 Protection against electric shock. Live working

This part of IEC 61243 , which is a Technical Report, is applicable to portable non-contact voltage detectors (NCVD) with built-in power source, to be used to indicate the presence or the absence of the operating voltage on electrical systems for nominal voltages above 1 kV AC and frequencies of 16 2/3 Hz, 50 Hz and/or 60 Hz.

NOTE

16,7 Hz is often referenced.

This document applies only to devices that are not designed to be used in contact with the bare part of the installation on which the presence or the absence of the operating voltage has to be tested.

This document describes only devices, and their behaviour, using electric field and voltage gradient detection principles even if other principles could be used. It provides performance guidelines, recommendations for use and recommended minimum criteria for selection.

Devices like personal safety distance voltage detectors, distance voltage detectors for emergency responders or machine operators are not covered by this document.

Except when otherwise specified, all the voltages defined in this document refer to phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages are used to determine the operating voltage.
