GDHX-8300F Wireless Phase Detector
GDHX-8300F Wireless Phase Detector is mainly used for phase sequence identification and labeling of power transmission and distribution lines.
Its working principle is: the phased base station regularly collects the phase signal of a certain area line as a standard signal and uploads it to the main station server. During measurement, the sensor collects the measured line signal and sends it to the handheld device. The handheld device applies to the server for the data of the phasing base station at the same time. By comparing the two phase data, the true phase of the measured line can be calculated.
The complete set of equipment mainly consists of the main station server, phasing station, handheld machine, sensors and accessories.
