IoT based Overload Protection System for Three Phase Induction Motor

The main aim of this research work is to develop an integrated approach for protection system using sensor-based microcontroller and IOT techniques. In this proposed method, a Graphical User Interface using NodeRed was developed to demonstrate the proposed system. The performance of the developed system is evaluated by testing the accuracy of current and temperature according to overload. The proposed system has 90% of accuracy of current. The proposed system consists of manually control and automatically control to cut the three phase power supply to protect the induction motor. Finally, the system proved to be very convenient in protecting and monitoring the state of three phase induction motor.
