Abstract
When the positive-phase voltage of one terminal of a transmission line involved in a fault detected by a positive-phase relay exceeds a predetermined value, an output is supplied to the reclosing instructing device from an AND circuit to first reclose this terminal. When it is less than the predetermined value, this terminal is reclosed only if reclosing of the other terminals have been successfully completed.
