Smart wireless sensor networks for online faults diagnosis in induction machine ?
A new method has been proposed for online faults diagnosis in induction motors based on smart WSN combined with motor current signature analysis using FFT. The proposed method is novel as it is important to install low cost sensors and detection mechanisms along with induction machines to achieve short detection time and an automated way of reporting the fault. The system can distinguish a faulty motor from a healthy motor with a probability of 99% with less than 5% of false alarm. Simulation results presented show the efficiency of the proposed method to detect faults in induction machine.
