Analysis and Controlling of Distribution Transformer Parameter using AVR Microcontroller IoT System

Distribution transformers are among the foremost important equipment in power network. As the massive number of transformers distributed over a wide range in power electric systems, the information acquisition and condition monitoring are the crucial issue. Distribution transformers can not be operated at 100% efficiency in non rated condition, as the load is user dependent and it is not possible to control the user load. The main focus of this research work is the monitoring and controlling of distribution transformer using Internet of Things (IoT). If the transformer gets affected due to any of the reason that is voltage, current, temperature or humidity, it can be monitored and the necessary requisites can be provided to the distribution transformer within the appropriate time. The monitoring and controlling of temperature, humidity, voltage and current of distribution transformer is performed based on the AVR micro-controller ATMEGA 328P. After interfacing the specified components such as AVR microcontroller, sensors, Wi-Fi module and relay the proposed application programming in embedded-C is implemented in AVR microcontroller ATMEGA 328P. The sensing of relay with continuous reading of temperature, humidity, voltage, current values and same has been displaced on the LCD(16 × 2) screen and sending all the data of transformer to the web-server of ThingSpeak in real time using a Wi-Fi module commonly known as ESP 8266.
