Live working - Phase comparators - Part 2: Resistive type to be used for voltages from 1 kV to 36 kV a.c. (IEC 61481-2:2014); German version EN 61481-2:2014
Arbeiten unter Spannung - Phasenvergleicher - Teil 2: Resistive (ohmsche) Ausführung für Wechselspannungen über 1 kV bis 36 kV (IEC 61481-2:2014); Deutsche Fassung EN 61481-2:2014
Overview
This part of IEC 61481 is applicable to portable phase comparators of resistive type to be used on electrical systems for voltages from 1 kV a.c. to 36 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to phase comparators of resistive type used in contact with the bare conductive parts to be compared as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard. Some restrictions on their use are applicable in the case of factory-assembled switchgear and on overhead systems of electrified railways. A device that is designed to provide other functions than phase comparison is a different device and is not covered by this standard. For example a device designed to be also used as a voltage detector is not covered by this standard. For this standard, the first edition of IEC 61481:2001 was fundamentally revised and divided into two parts: - Part 1: Capacitive type to be used for voltages exceeding 1 kV a.c.; - Part 2: Resistive type to be used for voltages from 1 kV to 36 kV a.c. The responsible committee is Subcommittee UK 214.4 "Ausrüstung und Geräte zum Arbeiten unter Spannung; Prüfgeräte, Isolierstangen und Vorrichtungen zum Erden und Kurzschließen" ("Equipment and devices for live working; test apparatus, insulating rods and devices for grounding and short circuiting") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
