Incoming side and outgoing side of the voltage sensor
6 Voltage sensor（built-in）
Phase voltage：（24（36）kV/√3）/（3.25V/√3）
Special attention should be paid to the voltage sensor, which must be directly fed by the switch.
No additional adjustment circuit can be added to the controller. The voltage signal of the switch into the test line needs to be tested separately.
