Research on the Influence of Inductively Coupled Wiring Methods on Oscillating Waves

The different wiring methods of the induction winding have a significant impact on the equivalent circuit parameters of the transformer winding, that is, the oscillation wave curve will undergo significant changes under different wiring methods of the induction winding. Due to the mandatory requirement for the induction winding to be grounded at a single terminal or short-circuit during the high-voltage test of transformers, this section mainly conducts systematic research on these two types of induction winding wiring methods. For the convenience of theoretical analysis, a single-phase dual winding transformer is taken as an example to conduct theoretical analysis and research. On the basis of the experimental platform, the correctness of the theoretical analysis is verified, and the optimal wiring scheme for on-site transformer oscillation wave testing is provided.
