KRM169E - INSULATION RELAY FOR NON-GROUNDED LIVE DC MAINS Insulation relay for non-grounded live DC systems Self powered from any input from 12 to 60VDC Both for battery and power generated DC networks "SEV" measuring principle For use in land, marine and offshore installations The digitally controlled low cost KRM169E is self powered and uses the Megacon SEV insulation measuring principle to measure the insulation in live non-grounded DC systems. The resultant insulation level is measured between the complete galvanically interconnected DC network and its protective earth. The signals flow to ground via the path of the insulation fault, the level of flow expresses the insulation resistance, the direction of flow expresses the fault polarity.
