whether the switch cabinet is live or not, it is not a standard nuclear phase
point, and the live displays of different manufacturers, different periods
and different standards will have different degrees of phase shifting
problems, and the corresponding relationship between the live displays
L1, L2, L3 and the bus is not necessarily correct. If the nuclear phase
result is abnormal, the nuclear phase should be carried out on the primary
line
。
Remote Phase Detection
Use two instruments at the same time for remote nuclear phase, the
schematic diagram is as follows
：
First turn on the two receiving hosts, switch to remote nuclear
phase mode, and complete the timing in the place where there is a GPS
signal, until the voice broadcast transmitter has no signal. Then the Y
