Electrical safety in low voltage distribution systems up to 1000 V a.c. and 1500 V d.c. Equipment for testing, measuring or monitoring of protective measures - Phase sequence algolia-ignore Transverse sensitivityWhat 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
