High-Frequency Oscillations in Induction Machine Stator Winding at Impulse Test with and without Rotor

Changes of equivalent circuit parameters which occurs in induction machines with increase of frequency are analysed. It is shown that high-frequency oscillations appear in first coil of grounded phase winding. The influence of rotor and stator insulation can be better monitored through oscillations in first coil of the grounded phase of the motor than through fundamental oscillation in equivalent circuit.
