Numerical Over Current and Earth Fault Relay

Prok dv’s make IDMT/DEFINITE TIME/INSTANTANEOUS LOW-SET/HIGH-SET NON-DIRECTIONAL NUMERICAL/MICROPROCESSOR BASED OVER CURRENT RELAY (OCR) WITH EARTH FAULT RELAY (EFR) of KP series PNA TYPE is extensively used for selective over current and earth fault protection of radial feeders in solidly earthed, resistance earthed or impedance earthed power systems. It has wide applications in substations and industrial networks.

The  IDMT/DEFINITE TIME/INSTANTANEOUS LOW-SET/HIGH-SET NON-DIRECTIONAL NUMERICAL/MICROPROCESSOR BASED OVER CURRENT RELAY (OCR) WITH EARTH FAULT RELAY (EFR) of PNA TYPE can also be used in most application where inverse time, definite time and instantaneous relays are required. The relay gives selective phase and earth fault protection in time graded systems for transformers, motors, etc. if ensures reliable protective system and clears only the faulted section.
