Power Transformer Decoupling and Simulation of Voltage and Current of Winding Insulation Defect

Abstract

In this paper a decoupling method is proposed according to the block of each phase winding. According to the relation, the current signals in each set of parameters can be corresponding to a single set of voltage signals. Simulation analysis of transformer model is carried out. The simulation results show that there is a difference between the voltage and current in different winding states. It has laid a foundation for the diagnosis of transformer winding deformation and other insulation defects.
