Abstract(s)
This paper presents the development and implementation of a coupled electromagnetic transformer model
for the simulation of three-phase power and distribution
transformers affected by the presence of winding inter-turn
short-circuits. Generically, the coupled electromagnetic
transformer model is based on the simultaneous consideration of both magnetic and electric equivalent circuits. To incorporate the internal faults in this model a suitable equivalent
circuit of the faulty winding is proposed. Both simulation and
laboratory tests results are presented in the paper, which
demonstrate the adequacy of the proposed model.
