Siguria elektrike në sistemet shpërndarës me voltazh të ulët deri në 1000 V rrymë alternative dhe 1500 V rrumë të vazhduar - Pajisja për mostrën. matjen ose monitorimin e masave mbrojtëse - Pjesa 9: Pajisja për vendndodhjen e gabimit të izolimit në sistem

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 - Part 9: Equipment for insulation fault location in IT systems

Scope

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.
