The goal of this paper is to protect induction motors against possible failures by increasing the reliability, the efficiency, and the performance. The proposed approach is a sensor-based technique. For this purpose, currents, voltages, speed and temperature values of the induction motor were measured with sensors. When any fault condition is detected during operation of the motor, PLC controlled on-line operation system activates immediately. The performance of the protection system proposed is discussed by means of application results. The motor protection achieved in the study can be faster than the classical techniques and applied to larger motors easily after making small modifications on both software and hardware. © 2007 IEEE.
