Background
The CVT is formed by combining a capacitance unit and an electromagnetic unit, one of the two units presents capacitance and the other presents inductance, when the parameters of the two units are matched, the CVT normally finishes the work of metering and protecting information transmission, and when a fault occurs in the two units, a new distributed capacitance or distributed inductance can be generated, so that the noise is increased when the CVT operates, and the overvoltage and the internal fault of the CVT can be generated due to long-term resonance. For the resonance of the CVT, although the resonance can be measured by the distributed parameters when the operation is interrupted, it is difficult to directly determine the resonance even if the parameters measured in the interruption are interrupted due to the lack of a very reliable distributed parameter model.
