Paper Title
PERFORMANCE MONITORING AND FAULT DETECTION OF ELECTRICAL MACHINES USING MICROCONTROLLER

Abstract
This work describes a condition based reporting technique of a multi-machine System using GSM technology. In this present approach, a dedicated microcontroller based hardware unit (DHU) has been developed to continuously measure the parameters of the motors viz. voltage, current, speed etc. to monitor the running condition of each motor in a plant. In a machine monitoring system the motor is connected with one such DHU, which are also connected to a Global System for Mobile Communication (GSM) modem. The preliminary level of fault or abnormality in operation of each machine is diagnosed by the respective DHU and the fault or abnormalities details are reported to the pre-assigned operator through an SMS service. In extreme case, the provision of machine shut down by a return SMS is also provided. A proto-type lab model is set up and is working satisfactorily.
