INVERSETIME OVERCURRENT RELAY Zoran N. Characteristics of inverse time over current relays In this type of relays operating time is inversely changed with current. The relay has two electromagnets. When the fault current is higher the operating time is faster and vice versa 12. Used to co-ordinate over other definite time or instantaneous protection. Inverse time delay is achieved in induction disc relay by providing a permanent magnet in such a way that when disc rotates it cuts the flux of permanent magnet.

Djuric This paper presents a new table based algorithm for overcurrent relay with inverse-time characteristic. Slow to trip at low currents. Modeling and Simulation of Inverse Time Overcurrent Relay using MatlabSimulink. When the fault current is higher the operating time is faster and vice versa 12. The algorithm is based on loading the adequate time vector through which inverse-time characteristic is modeled. The rms current represents an.
