Dear brothers
Attached file shows actual wiring for directional earth fault protection relay.
This relay is set to trip in the forward direction with V, I angle = 15
according to the wiring you will see that the earthing point of the C.T secondary is towards the transformer. This as far as I know means that the forward direction is when the earth fault current follows towards the transformer.
I hope that you will find this usefull and I hope to receive your comments
My deep regards to you all
