KPC112E protects against phase-, earth- and winding faults within the protected area (the stator) of large AC generators. It detects even minute insulation punctures, flash-over carbon deposits and contamination. The unit measures highest up differential current from antiparallelled CTs in a Merz-Price configuration, by comparing current levels at the end of each phase winding. Special features: -Generator Stator earth fault Protection -Winding insulation Protection -"Pathfinder" function eases faultfinding -For use with 1A or 5A current transformers -Very fast analogue output (<50mS), (F-version) Bornika is the exclusive representative of megacon company, in purchasing , sales, consulting and distribution of industrial equipment including Earth Leakage and Earth Fault Protection Relay.
