Abstract

The invention relates to design of protection feature in a self powered protection relay. It specifically provides a relay with sensitive earth fault protection. This protection is being achieved in tandem with optimal power on trip time (switching to fault) and with integrated logic for inrush discrimination. The self supplied protection relay is provided with a current processing module adapted to measure and evaluate line current to generate trip signal. The current processing module has the capability of inrush current suppression to block earth fault detection during an inrush condition and thereby increase sensitivity of fault detection.
