Abstract: This work presents the use of terminal capacitance measurements to detect deformations in transformer windings. The lumped parameter representation of windings is considered. The deformation coefficient (DC) derived from the measurements is used to detect winding deformations. The extent and location of deformation can also be determined by this method. This paper presents the mathematical basis underlying the method of using DC for windings. The formulation of DC is also explained. Simulation results are given to demonstrate the applicability of the method for deformation diagnostics.
