IEC/TR 61243-6 (2017-03)

IEC TR 61243-6:2017(E) 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 voltage_s above 1 kV AC and frequencies of 16 2/3 Hz, 50 Hz and/or 60 Hz. 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.
