Abstract :
Time domain terminal models for high voltage induction motor windings are developed for simulating transient overvoltages due to switching operations in industrial installations. The models are based on the network synthesis of the terminal impedance for short circuit and open circuit conditions of the winding. The process of synthesis is carried out taking into account the minimum and maximum resonant frequencies. The machine winding impedance is determined with a frequency domain model developed by means of the transmission line theory and using a finite element method for electrical parameter calculation. The computer models are validated by comparing the calculated transient overvoltages and the winding impedances against test data for a high voltage motor
