适用范围：This part of IEC 61557 specifies the requirements for measuring equipment applied to testingthe phase sequence in three-phase distribution systems. Indication of the phase sequence maybe mechanical, visual and/or audible.This part of IEC 61557 does not apply to ancillary measuring equipment for other quantities, forexample voltage testers comprising an additional phase sequence indicator. It does not applyto monitoring relays.NOTE Phase lamps are not considered to be voltage testers.
