Abstract :
In distribution network, when phase detector is made between two high voltage switchgear, with which the capacitive sensor indicators assorted are inconsistent, some problem like phase sequence detection misjudgment could occur. In order to solve this problem, phase difference method is proposed for the phase sequence detection between the two high voltage switchgears. This method has the versatility to judge accurately in phase detection. Actual test shows it could fully meet the phase dection requirements of high voltage switchgear.
