The HZHX-V Wireless Non-Contact High Voltage Digital Phase Detector is a network-based phase tester designed for phase sequence identification and labeling of transmission and distribution lines. It delivers reliable phase verification even in environments without GPS, BeiDou satellite positioning, or mobile network coverage.
The system works by collecting the phase signal of a given area line at regular intervals through a phase-fixing base station, which uploads this standard signal to the main station server. During measurement, the sensor collects the signal of the line under test and sends it to the handheld unit. The handheld then requests the corresponding base station phase data from the server at the same moment, and the true phase of the measured line is calculated by comparing the two phase data sets.
The complete equipment set consists of a master server, phase-fixing base station, handheld unit, and transducers.
