A Calculation Method for Impulse Voltage Distribution and Transferred Voltage in Transformer Windings

Abstract

This paper presents a calculation method for impulse voltage distribution in the complex winding arrangement encountered in large power transformers. This method takes into account the electrostatic and electromagnetic combinations of windings, and, therefore, permits a precise analysis of voltage response in the windings to which an impulse voltage is applied and of the transferred voltage in other windings to which an impulse voltage is not applied directly.
