DESCRIPTION

BS EN 61557-13:2011


This standard BS EN 61557-13:2011 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. Equipment for testing, measuring or monitoring of protective measures is classified in these ICS categories:
  • 17.220.20 Measurement of electrical and magnetic quantities
  • 29.080.01 Electrical insulation in general
  • 29.240.01 Power transmission and distribution networks in general

This part of IEC 61557 defines special performance requirements for hand-held and hand-manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems up to 1 000 V a.c. and 1 500 V d.c., taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. This standard does not apply to current clamps or sensors which are used in combination with devices for insulation fault location according to IEC 61557-9, unless it is specified by the manufacturer.
