Calculation of Capacitance and Inductance Parameters of Transformer Winding under very Fast Transient Overvoltage

Abstract:

The distributed parameters of transformer windings are indispensable in analyzing the transients particularly caused by the very fast transients which occur at the time of disconnecting switch operations in GIS. Winding insulation structure and the safe and stable operation of the transformer are determined by the accuracy of the calculation. In this paper, finite element method (FEM) is used to model and simulate the electromagnetic field calculation of winding capacitance and inductance parameters. The simulation calculation results are consistent with the experimental measurements on a transformer model, which verifies this method is feasible.
