PROK DEVICES PVT LTD an ISO 9001-2008 company introduces DIGITALMICROPROCESSOR / MICROCONTROLLER BASED IDMT / DEFINITE TIME / INSTANTANEOUSEARTH FAULT RELAY (EFR).It is a current sensing device which is tropicalised professionallydesigned and tested for protection of Generators, Transformers and Feeders. Prok dv'smake DIGITAL MICROPROCESSOR / MICROCONTROLLER BASED IDMT / DEFINITE TIME /INSTANTANEOUS EARTH FAULT RELAY (EFR) can be employed with various earth fault protectiveschemes, which are explained in brief with figures. The magnitude of the earth fault currentdepends on the fault impedance and invariably the fault impedance for earth fault ishigher than that for phase faults, hence the earth fault current is low compared to thephase fault currents. The fault impedance depends on the system parameter and also ontype of earthing. The neutral may be solidly grounded, grounded through resistance orreactance.   Specification Compact IDMT (4 IEC curves), Definite Time & Instantaneous Wide setting ranges Fully digital acquisition & processing of data Wide operating voltages LCD display of operated current & fault current Rugged and Tropicalized design
