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.

GDYZ-302W Metal Oxide Arrester (MOA) Tester
GDYZ-302W Metal Oxide Arrester Tester is is composed of a host, a detector, and an insulating rod. The host and the detector adopt wireless communication, the communication distance is 30 meters, the host can remotely open or close the clamp head of the detector to complete the test process, and the host can display the current test value and the status of the clamp head in real time. The detector uses a micro motor to drive the opening or closing of the clamp head. The clamp head is made of high-performance permalloy, which has super anti-interference ability and is hardly affected by external magnetic fields. The resolution is as high as 1uA. The detector can be connected to an insulating rod for testing of zinc oxide surge arresters on high-voltage lines. The meter can also be used as an ultra-high-precision clamp-on leakage current meter.
