Modeling and Characterization of Transformers Internal Faults Using Finite Element and Discrete Wavelet Transforms

Abstract

This paper investigates the behavior of three phase transformers with internal faults under sinusoidal and nonsinusoidal operating conditions. The terminal behavior of the transformer was investigated by coupling the finite element transformer's physical model with external electric circuit equations. Two types of internal faults were modeled turn-to-ground… (More)
