Induction machine fault diagnosis using microcontroller and Real Time Digital Simulation unit

In an approach to diagnose the various types of fault, generally occurred in Induction machines, this paper describes a monitoring and analysis system. The induction machine model and its various types of fault are simulated using a Real Time Digital Simulation (RTDS) unit. The signal corresponding to the simulation can be taken out of the RTDS unit which is interfaced with a microcontroller for its acquisition in a PC. The PC based software can store it and the fault detection algorithm (sequence component based) runs over it to detect and diagnose the fault. Encouraging results are obtained.
