KRM161-DC

 
KRM161-DC - INSULATION RELAY FOR INACTIVE NON-LIVE DC SYSTEMS
  • Insulation "megger" for non grounded non-live DC circuits
  • 0-110VDC system voltage
  • "IDV" measuring principle
  • For use in land, marine and offshore for alarm-lamps, Lantern, DC motors etc.
KRM161-DC monitors resultant insulation level between a non-grounded non-live DC network and its protective earth.  

The trip level is preset at factory and relay will operate when insulation is below trip level after a delay of
2-5 seconds. Relay is fail-safe and energises when powered. Link terminal 15 and 16 to make a non-latching relay.

KRM161-DC unit injects a DC voltage signal into the monitored network and measure the earth leakage flow to the ground. Only one unit can be connected to each isolated system. Terminal 1 and 2 must be disconnected when network is powered.
