Application of the Sinusoidal Voltage for Detection of the Resonance in Inductive Voltage Transformers

In the case of the inductive voltage transformer (VT), the resonance phenomenon may be the main reason for its poor transformation accuracy of the non-sinusoidal voltage. This problem mainly results from the leakage inductance and the parasitic capacitance of its primary winding. The application of...
