DESCRIPTION

BS EN 61557-9:2000


This standard BS EN 61557-9:2000 Electrical safety in low voltage distribution systems up to 1000 V a.c. and 1500 V d.c. Equipment for testing, measuring ormonitoring of protective measures is classified in these ICS categories:
  • 25.040.40 Industrial process measurement and control
  • 17.220.20 Measurement of electrical and magnetic quantities
Specifies the requirements for insulation fault location systems which localize insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically d.c. circuits having nominal voltages up to 1000 V a.c., as well as in unearthed IT d.c. systems with voltages up to 1500 V d.c., independent of the measuring principle. This part is to be used in conjunction with IEC 61557-1.
