The HZHX-V Network Base Station Phase Tester is designed for phase sequence identification and labeling of transmission and distribution lines. It delivers reliable, accurate phase verification even in environments without GPS, BeiDou satellite positioning, or mobile network coverage.

Working Principle: A phase fixing base station periodically collects the phase signal of a given area line as a standard reference signal and uploads it to the main station server. During measurement, the sensor collects the signal of the line under test and transmits it to the handheld unit. The handheld then requests the corresponding phase fixing base station data from the server for the same moment, and the true phase of the measured line is calculated by comparing the two phase data sets.

The complete system consists of four main components: the master server, the phase fixing base station, the handheld unit, and the transducers.
