Abstract(s)

This study 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 turn-to-turn winding insulation failures, and to distinguish them from magnetising inrush current transients. Experimental and simulation results are presented and discussed.
