Condition Monitoring and Feature Extraction of Stator Current Phasors for Enhanced Fault Diagnosis in AC Drive

AC drives are employed mainly in process plants for various applications. In most industrial applications, Induction motor preferred as they robust, reliable, and efficient. Process industries have seen a paradigm shift from manual control to automatic control. Advancements power electronics technology led smooth of the induction using variable frequency over an entire speed range. Variable Frequency Drives (VFD) comprises Voltage source inverter three phase squirrel cage motor. Various electric faults that incipient VFD cause abrupt change circuit parameters resulting insulation damage, reduced efficiency, leading catastrophic failure system. Hence, continuous monitoring system such stator current, speed, vibration machine is essential diagnose AI techniques been effectively used fault diagnosis electrical systems. proposed work, simulation results learning-based presented. Real-time IoT-based condition Drive also implemented enhanced drives. The experimental obtained validated with data.
