Earth Fault Relay

Prok Devices offers an Earth Fault Relay for protection of electrical equipment from earth faults. This relay is a current sensing device that is tropicalised and professionally designed and tested for protection of generators, transformers and feeders. It can be employed with various earth fault protective schemes, depending on the equipment. The magnitude of the earth fault current depends on the fault impedence and invariably the fault impedence for earth fault is higher than that for phase faults, hence the earth fault current is low compared to the phase fault currents. The fault impedence depends on the system parameter and also on type of earthing. The neutral may be solidly grounded, grounded through resistance or reactance.
