Analysis of Technical Parameters of YHX-300G Remote Wireless High-Voltage Phase Verifier



The YHX-300G remote wireless high-voltage phase verifier adopts GPS timing technology and wireless transmission technology, used for long-distance phase verification, short-distance phase verification, and phase verification at switchgear power-taking induction points. It also has functions of high-voltage live detection, phase sequence verification, and grid frequency measurement. The instrument is suitable for live phase verification operations on 5V to 500KV transmission lines. 

The YHX-300G remote wireless high-voltage phase verifier uses GPS satellite timing technology to obtain unified time anywhere in the world, and can simultaneously measure the phase difference between two wires in any location. This solves the distance limitation of traditional wireless phase verifiers, which require operation within 300 meters.

Working Principle

Long-distance phase verification - Measurement mode: Master units A and B are timed by GPS, and at the same GPS time (nanosecond level) start receiving phase and frequency information from transmitter Y, calculating the phase difference based on the phase values of A and B.

Long-distance phase verification - Timing measurement mode: Master units A and B are pre-timed by GPS, then start their internal clocks, and at the same timemicrosecond level start receiving phase and frequency information from transmitter Y, calculating the phase difference based on the phase values of A and B.

Short-distance phase verification: One master unit measures and receives signals from transmitter X and transmitter Y, calculating the phase difference between the two lines.

Transmitter principle: Collects phase and frequency information of live lines, encodes the information, and sends it to the receiving master unit via radio waves.
