Research on the electrical resonance characteristics of power transformer windings
When a power transformer subjected to transient over-voltages containing different harmonic components, the frequency components of over-voltages are coupled with the inherent electrical frequency of the transformer winding, which can induce high-amplitude resonant over-voltages in the winding and thus lead to transfor...
