What is BS EN 61557-7 – Testing equipment for electrical safety system about?
BS EN 61557-7 is a part of IEC 61557.
BS EN 61557-7 specifies the requirements for measuring equipment applied to testing the phase sequence in three-phase distribution systems. Indication of the phase sequence may be mechanical, visual and/or audible.
BS EN 61557-7 does not apply to ancillary measuring equipment for other quantities, for example voltage testers comprising an additional phase sequence indicator. It does not apply to monitoring relays.
Note: Phase lamps are not considered to be voltage testers.
