Over current and under voltage monitoring system of a three phase induction motor based on IoT

Abstract

Sudden fluctuations in voltage may cause a serious problem in industriesand home application.These fluctuations may significantly impact the power quality and reliability of other voltage-controlling devices. However, this proposed project discussed about the design for under-voltage and over-voltage protection to protect and extend the security of the home, office, and industrial equipment. LDR is used here to detect the voltage of a few percentages below the rated voltage and it is recognized as under voltage while a few percentages of the rated voltage are recognized as over voltage. We are using 3 phase induction motor. Moreover, the sensor is attached to the board WiFi platform so that the user can observe the voltage condition through Blynk application.In conclusion, the combination of voltage protection systems through the Internet of Things (IoT) devices may contribute to the user
