What are the Characteristics of PT Disconnection?

PT disconnection can generally be divided into PT primary side disconnection and secondary side disconnection. No matter which side of the disconnection, the voltage of the secondary circuit of PT will be abnormal.

When the PT primary side disconnects, one is all disconnects, at this time, there is no voltage on the secondary side and no voltage on the opening triangle; The other is asymmetric disconnection, at this time, there is no phase voltage on the secondary side of the corresponding phase, the secondary voltage of the continuous line phase is unchanged, and the opening triangle has voltage.

In the case of PT secondary side disconnection, there is no voltage in PT opening triangle, and the phase voltage of disconnection phase is zero.
