PROJECT TITLE :

Extended Park's vector approach-based differential protection of three-phase power transformers

ABSTRACT :

This study presents a replacement scheme for power transformers protection, that is based on the analysis of the harmonic content of the differential current Park??s vector modulus. The proposed methodology 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.
