IoT Based Monitoring of Distribution Transformer

Distribution transformer used for the circulation of electricity. It provides the final voltage transmission in the electrical power distribution system, stepping down the voltage used in distribution lines to the level used by customers. So, maintenance of distribution transformer is a daunting task for Electric Board department to monitor those transformers regularly. This paper presents an idea to follow the transformer online by analyzing its various parameters like temperature, voltage, current, and oil level. For this, sensors are used to sense the actual readings from different parameters with the help of the microcontroller. Data of operation and abnormal condition of transformer receives in the IoT module, and this data saved in computer server from where we can monitor these parameters on system screen with the help of a particular web address. Using the suggested online monitoring system will help utility operators to keep transformers in service for a longer time.
