Abstract
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.
