Abstract(s)

This paper presents a new scheme for power transformers protection, which is based on the analysis of the harmonic content of the differential current Park's Vector modulus. The proposed method is able to detect winding insulation failures, and to distinguish them from magnetizing inrush current transients. Experimental and simulation results are presented and discussed.
