The HZHX-V Network Base Station Phase Tester is designed for phase sequence identification and labeling of transmission and distribution lines. It provides a reliable solution for verifying line phases in high-voltage AC transmission environments.
Its working principle is as follows: the phase signal of a certain area line is collected by the phase fixing base station at regular intervals as a standard signal and uploaded to the server of the main station. During measurement, the sensor collects the signal of the measured line and sends it to the handheld unit, which applies to the server for the data of the phase fixing base station at the same moment. The real phase of the measured line can then be calculated by comparing the two phase data.
The complete equipment set mainly consists of a master server, phase fixing base station, handheld unit, and transducers.
