Abstract :
To investigate feature extraction methods for early detection of insulation degradation in low voltage (under 600 V), 3-phase, PWM controlled induction motors, a series of seeded fault tests was planned on a 50 HP, 440 V motor. In this paper, the background and rationale for the test plan are described. The instrumentation and test plan are then detailed. Finally, preliminary test experiences are related
