Directional over current protection

[tamerelminshawy]

An out going feeder is protected with over current protection relay which is supposed .does the point of current transformer earthing (l,k) affects the forward and backward directionality of the relay. and Is it possible to detect directionality without having votage measuring input circuits in the relay.
Thank you for your assistance

If the relay is a standard non-directional over current relay then the direction of CT secondary has no effect on the relay pickup.

A directional relay must have a polarizing reference so that it can measure the direction (the polarizing value is always voltage input)
