Automatic Switching of Three Phase Induction Motor during Fault Condition

This paper proposes the automatic switching of a three-phase induction motor to provide an uninterrupted motor operation in industrial applications. To accomplish this aim, two motors are employed one is a primary motor and another one is a back-up machine that is automatically made switched on in the case of primary motor fails to operate. All the process is controlled by the Arduino controller design. Moreover, the continuous running of motors causes the motor temperature to rise, which is effectively handled by the proposed controller design, which automatically switches the primary and backup motor for every 24 hours. The motor operating status is automatically updated by means of GSM strategy to the operator. Here arduino controller used to control the induction motor with the help of relay. In the case of unexpected fault conditions, to protect the system both the motors are automatically switched off and a message is passed to the operator about the fault condition. The proposed methodology is experimentally validated by a hardware model with better working performance.
