In earth fault protection the feeder or drive is protected
against an earth fault.In restricted earth fault protection
the complete winding of transformer or generator is not
protected against earth fault depending upon the value of
resistance connected in neutral grounding.If the earth
fault occure in the part of unprotected portion of winding
the eart fault relay will not trip
