Abstract

PURPOSE: To enable synchronous connection so long as the synchronous state holds irrespective of the state of the system by detecting the phase of one of two different voltages with the position of the other voltage made as reference and thereby permitting the derivation of the leading or lagging relation of the phases of both the voltages.
