This remote wireless high-voltage phasing device using GPS accurate timing technology and wireless transmission technology for very long distance phasing, short distance phasing and RMU induction point phase identification, also with high voltage detection, phase sequence and frequency checking function, suitable for 5V ~ 500KV transmission line live operation.

The instrument includes two set of phasing testers (two carrying boxes, separate one can be used for short distance phasing), each set contains one receiver, X Y transmitter, and telescopic insulation probes which are high voltage insulating parts, moisture-proof, high temperature resistance, anti-bending.
