Abstract
PURPOSE: In order to enhance accident detection capability and the cooperative characteristics between a high and low sensitivity device, devised is to organize a circuit by a compensation voltage unit which simulates under the condition that there is no accident between a terminal and a branch point, and a high and low sensitivity voltage fluctuation relay unit which responds to the compensation current.
