“Online Off-Site Condition Monitoring Of Three Phase Induction Motor by Using GSM Technology”

This paper describes online off-site condition monitoring of three phase induction motor by using GSM technology. In this approach, a microcontroller based hardware unit has been developed to continuously monitoring and measure the stator current of the motors. In a motor monitoring system the motor is connected with one microcontroller based hardware unit, which is also connected to Global System for Mobile Communication (GSM) modem. The preliminary level of fault or abnormality in operation of motor is diagnosed by the Fast Furrier Transform in MATLAB and the fault details are reported to the assigned operator through an SMS service. In extreme case, the provision of motor is shut down by a return SMS is also provided. A lab model is set up and is working satisfactorily.
