Contributor Popov, M. (mentor) Smit, J.J. (mentor) Faculty Electrical Engineering, Mathematics and Computer Science Department Electrical Power Engineering Date 2009-07-10 Abstract The thesis describes the modeling of the internal faults in three-phase three-winding power transformer related to the differential relay protection behavior due to those faults. This transformer model is based on the mutually coupled [RL] matrix and entirely compatible with ATP/EMTP software. The model uses the real power transformer and the simulation is based on the real condition in the substation. The results enable one to understand the current waveform when the turn-to-earth and turn-to-turn fault occur at the transformer. The transformer differential relay protection operation and characteristics due to those internal faults are also studied.
