Abstract
PURPOSE: To make operation of relay to be sure, by providing an integral circuit which starts integration by synchronizing to riser of rectangular wave which was obtained by converting alternating current in each series of positive wave and negative wave of alternating input, and level detecting circuit which compares this integral output with set level.
