Abstract
This paper presents a new method for discrimination between faults and inrush current in transformers using the energy profile of the current. In this approach, the discrete wavelet transform has been used to extract the energy of the signal at 15 resolution levels. It is shown that the energy profile of wavelet decomposition levels leads to the accurate discrimination between fault and inrush current.
