Distance Relays or Impedance Relays: The operation of the relays discussed so far depended upon the magnitude of current or power in the protected circuit. However, there is another group…

Induction Type Directional Overcurrent Relay: The directional power relay is unsuitable for use as a directional protective relay under short-circuit conditions. When a short-circuit occurs, the system voltage falls to…

Induction Type Directional Power Relay: This Induction Type Directional Power Relay operates when power in the circuit flows in a specific direction Unlike a non-directional overcurrent relay, a directional power…
