transmitter will be contacted with the live line under test. At this time, the
two receiving hosts will record a set of data every 10 seconds,No1 to No6
are the data of 0s, 10s, 20s, 30s, 40s and 50s per minute respectively.
Compare the data of the same number of A and B to judge the same and
different phase. The display interface is as follows
：
A machine
B machine
Reminder
：
(1) if there is no GPS signal at the test site (such as the underground
power distribution room), it is necessary to first connect the receiving
host to the GPS satellite signal in the outdoor place where there is GPS
signal, and then get the place without GPS signal for measurement, and
the host will automatically switch to the time service mode. At this time,
the host uses the internal clock, whose accuracy is worse than the GPS
clock, and the error will accumulate. Please complete the test within 30
minutes of time service, otherwise, it is necessary to reconnect the GPS
signal to calibrate the clock to ensure the test accuracy.
