Winding faults are the leading cause of power transformer failures. Usually these failures develop in to more serious faults that would result in irreversible damage to the transformer winding and the consequential costs. This contribution is aimed at locating the faults by defining a set of two parameters based on change in impedance due to fault in the winding. Modeling and measurement of 22 kV continuous disc winding is done using circuit simulation package and sweep frequency response analyzer respectively.. The identified parameters are used in localization of faults in the transformer winding. The proposed method for localization of fault by measurement is validated by modeling.
