Abstract
PURPOSE: In a carrier protection relay system descriminating outside and inside of a failure by mutual connection of a result of determination of orientation of failure respectively on both ends of a power supply line, to prevent a false action by a zero-phase circulating current which causes a problem at a paralleled multiple connection and to allow a positive operation when a failure is caused inside the area.
