SENSOR BASED FAULT IDENTIFICATION AND PROTECTION OF INDUCTION MOTOR

Protection of an induction motor (IM) against possible problems, such as overvoltage, over current, overload, over temperature, and under voltage, occurring in the course of its operation is very important, because it is used intensively in industry as an actuator. IMs can be protected using some components, such as timers, contactors, voltage, and current relays. the voltages, the currents, the speed, and the temperature values of the motor, and the problems occurred in the system, are monitored and warning messages are shown on the computer screen. This paper focuses on experimental results to identify and protect faults in 3-phaseinduction motors using LabVIEW.
