Automatic Inverse Time Protective Relays IDMT Overcurrent Protection Time overcurrent relays operate with a time delay, which is adjustable. For given setting, the actual time delay depends on the current through the relay coil. Higher current will cause a faster operation of the relay. The minimum relay operation current (pick-up current) is also adjustable. The most commonly used overcurrent relay has both the instantaneous response for very large currents and the inverse
