Product Introduction
Remote wireless high-voltage phase detector
（
Hereinafter
referred to as "instrument"
）
It is used for long distance(apart from 300
meters to 800 kilometers )to check whether the high voltage phase is in
phase and whether the phase sequence color is marked correctly . It can
also be used for short distance grid connection or loop network core
phase. The instrument is suitable for live working of 5V-220kV
transmission line and live working of secondary side, It has high voltage
power test function.
The instrument adopts wireless transmission technology, which is
safe and reliable in operation and convenient to use, and overcomes many
shortcomings of the wired phase detector. And using GPS timing
technology, two (or more) instruments can be separated by hundreds of
kilometers of nuclear phase
。
Working Principle
The instrument is composed of A and B machines. A and B
machines can be used separately for short-range nuclear phase. In the
short-range nuclear phase, the X and Y transmitters send the measured
data to the receiving host by radio. The receiving host calculates the
phase difference between the two lines based on the transmitter data to
