Directional earth fault relay maloperation
Directional earth fault relay maloperation
(OP)
Directional earthfault relay receives VT input from the VT in the switchgear incomer cable box and CT input from that in the transformer neutral-to-earth connection. The relay is set to look away from the transformer.
Now, can some one tell me - whether the VT location is the reference for the directionality or the CT location? I think it is the CT location.
