In this tutorial video, we will calculate relay settings of Phase Overcurrent Relays installed for protection of parallel feeders. At certain locations, simple overcurrent relays are not adequate to provide protection to transmission lines. Additional directional discrimination is essential. We are adding one further complication to the relay setting procedure in this numerical. I hope YouTube viewers will enjoy and learn one more step in protection of transmission lines using overcurrent and earth-fault relays.
