What are the Effects of PT Disconnection?

Once the PT is disconnected and depressurized, the accuracy and reliability of protection, measurement, and measurement operations are greatly affected.

1. The voltage of the protection device will be deviated, and the correct acquisition of the voltage is a prerequisite for the correct operation of distance protection, directional locking and overcurrent protection with low voltage starting element.

2. The accuracy and reliability of the measurement data of the measuring device will be affected. The voltage of the measuring device is not only a basic electrical measurement parameter of the electrical measurement, but also provides power supply for some meters.

3. It will affect the accurate monitoring of the measured voltage quantity and make the operation monitoring of the voltage quantity lose reliable basis.
