Wireless HV phase tester

Type: ZC-820A

ZC-820A Wireless HV phase tester is used to detect whether the power supply on both sides of the closed-loop point circuit breaker of the ring network or dual power supply network is in phase. The instrument is suitable for the live phase verification of 500kV and below Bookstore lines, and has the functions of high voltage power test and phase sequence verification. It is mainly used for the phase verification and phase sequence verification of power lines and substations, mainly including power test, phase verification, phase sequence measurement, etc.
