Overview
This part of IEC 61481 is applicable to portable phase comparators of capacitive type to be used on electrical systems for voltages exceeding 1 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to: - single-pole phase comparators of capacitive type operating with a memory system up to 36 kV a.c.; - two-pole phase comparators of capacitive type operating with a wireless connection up to 245 kV a.c. This part of IEC 61481 is applicable to phase comparators of capacitive type used by contact with the non-insulated conductive parts of the installation to be tested, as a related type including insulating part or as a separate type allowing the connection of an insulating rod not covered by this document as a separate tool. Some restrictions apply to use on prefabricated switchgear and overhead contact lines of electric 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 DKE/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.
