Voltage sensors

CT ABC 10P10 5VA 400:05:00

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 LBS load break 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.
