Abstract
Protection of induction motor against possible problems such as overvoltage , overcurrent , overspeed , overtemperature , three-phase unbalanced occurs in course of it’s operation is very important because it is used intensively in industry as an actuator. Induction motor can be protected using some components, such as timers, contactors, voltage, and current relays. The voltages, currents,speed, and temperature are the parameters of the motor, andthe problems occurred in the system, are monitored by microcontroller ATMEGA-16 which communicates with GSM and GSM send messages are shown on the LCD as well as on the mobile screen. Experimental resultsare presented in this paper which shows that the parameters of induction motor can be monitored using GSM which costs less, provides higher accuracy as well as safe and motorgets fully protected.
