determine the phase difference.
。
Both machines can be used for remote phase verification. When the
remote phase detector is used, two Y transmitters send the measurement
data to two receiving hosts respectively. The host is measured
synchronously after timing by GPS. The phase difference between the
two hosts is calculated as the phase difference between the two lines to
judge the same and different phases of the two lines

Safety Precautions
1
、
During the field test, the operation shall be carried out according to the
safe distance standard for high voltage test of the power department
。
2
、
The standard configuration of the insulation rod is 3 meters, and the
corresponding voltage level is ≤ 220kV. If the measured line voltage is
higher than 220kV, please use an insulation rod with a length of more
than 3 meters
。
3
、
During nuclear phase operation, do not hold the position beyond the
handle of the insulation rod
。
Note: The transmitter uses a 3.7V rechargeable lithium battery,
please do not replace other batteries
