IEC - 61557-7

Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC – Equipment for testing, measuring or monitoring of protective measures – Part 7: Phase sequence

active, Most Current
Organization: IEC
Publication Date: 1 August 2023
Status: active
Page Count: 66
ICS Code (Power transmission and distribution networks in general): 29.240.01
ICS Code (Measurement of electrical and magnetic quantities): 17.220.20
ICS Code (Electrical insulation in general): 29.080.01
scope:

This part of IEC 61557 specifies the requirements applicable to measuring equipment for testing the phase sequence in three-phase distribution systems. Indication of the phase sequence can be mechanical, visual and/or audible.

This document does not apply to additional measurements for other quantities. It does not apply to monitoring relays.

NOTE Common three-phase distribution systems are depicted in IEC 61010-1:2010, Annex I and IEC 61010-1:2010/AMD1:2016, Annex I.
