WHC-300C Overview For 3-phase sequence and A/B/C phase difference measurement, also for phase verification. Suitable for 6kV~220kV live-line operation with HV detection. WHC-300C Applications Uses wireless technology for safe, reliable operation. Enables direct HV line phase sequence measurement. Complies with national safety standards. X/Y/Z transmitters send phase/frequency to receiver, which calculates phase differences and determines sequence.
