IOT based Transformer Health Monitoring System

This paper illustrates the Design and development of IOT based transformer health monitoring system using Arduino. As the Transformers are heart of power production and distribution. Damages of transformer effect on power distribution. Damages happen due to poor maintenance and overheating. Sometimes over load create very huge problem. But there is no transformer health monitoring system available in existing electricity department. In this paper we are proposing a solution like IOT based transformer health monitoring system. This paper includes WIFI (Esp8266 /IOT module), which is connected to Arduino through UART interface. Temperature sensor (LM35) connected to Arduino through analog pin. Shunt resistance and voltage divider connected to Arduino Analog pins respectively. Here, a load (bulb) and transformer may be connected. A current sensor measures the load's current value. Voltage sensors also read
voltage. This load variation circuit changes the load's voltage and current. Transformer temperature is read by an LM35 and updated on the LCD. Through WIFI (Esp8266/IOT
module), temperature, voltage, and current information will be updated on the IOT server. IOT server data is accessible to users from anywhere. Data may be seen in graphical
representation. Data may be seen in graphical representation. In this paper, a controlled 500mA, 5V power source is used. Voltage control is accomplished using the 7805 three terminal voltage regulators. The ac output from the secondary of 12V is rectified using a bridge type full wave rectifier.
