What is Maximum Torque Angle in Directional Relays about?

1) Directional overcurrent (OC) protection is necessary for transmission and sub-transmission systems with multiple power sources to ensure the correct relays operate for faults. 2) In a parallel feeder system, directional OC relays are needed to prevent both lines from tripping for a fault on one line and to ensure the faulted line isolates from its source. 3) Directional OC relays are also required for ring main feeder systems to allow power to continue flowing on the healthy sections after a fault is
