Inverse Time Overcurrent Relays And Curves Explained Pdf Relay This document discusses different types of directional over current relays. it explains that directional over current relays operate when fault current flows in a particular direction and will not operate if power flows in the opposite direction. Directional overcurrent protection is used to protect the system when fault currents could circulate in either direction along the network line. Construction of directional overcurrent relay : the schematic diagram of the directional overcurrent relay is shown in the figure given below. it consists of two relay units mounted in a common case, namely directional relay unit, and non directional or overcurrent relay unit.

The fundamental problem we face in designing an ac directional current relay is how to detect this phase shift between forward and reverse current. in our dc generator circuit, a reverse flow of current could easily be detected by monitoring the polarity of voltage drop across a series resistance. Overcurrent directional relays: these relays use the phase difference between the current and voltage to determine the direction of the fault. they are commonly used in power systems with radial or parallel feeders. Directional over current relay: a directional over current relay develops maximum positive torque when the current and voltage supplied to the current coil and the pressure coil are in phase. Induction type directional overcurrent relay: the directional power relay is unsuitable for use as a directional protective relay under short circuit conditions.
