Analysis of Technical Parameters of YHX-300G Remote Wireless High-Voltage Phase Checker
The YHX-300G remote wireless high-voltage phase checker uses GPS timing technology and wireless transmission technology for long-distance phase checking, short-distance phase checking, and phase checking at switchgear power-taking induction points. It also has the functions of high-voltage live detection, phase sequence verification, and grid frequency measurement. The instrument is suitable for live phase checking operations on 5V to 500KV transmission lines.
The YHX-300G remote wireless high-voltage phase checker uses GPS satellite timing technology to obtain unified time anywhere in the world, and can simultaneously measure the phase difference between two power lines anywhere. This solves the distance limitation of traditional wireless phase checkers, which require operation within 300 meters.
Working Principle
Long-distance phase checking - Measurement mode: The master units A and B are timed by GPS, and at the same GPS time (nanosecond level) start receiving the phase and frequency information from the Y transmitter, and calculate the phase difference based on the phase values of A and B.
Long-distance phase checking - Timing measurement mode: The master units A and B are pre-timed by GPS, then start their internal clocks, and at the same timemicrosecond level start receiving the phase and frequency information from the Y transmitter, and calculate the phase difference based on the phase values of A and B.
Short-distance phase checking: One master unit measures and receives signals from the X transmitter and Y transmitter to calculate the phase difference between the two lines.
Transmitter principle: Collects the phase and frequency information of the live line, encodes the information, and sends it to the receiving master unit via radio waves.
