Overvoltage in the coils of the interlaced winding of a high-voltage power transformer.

Abstract

A method for analyzing the transient process in intertwined coils has been developed, which consists in dividing the initial effect into several symmetrical effects, each of which corresponds to a component of the separation of currents and voltages. The role of capacitive parameters is revealed and the equivalent circuit is synthesized, which allows to determine the overvoltage inside the coils.
