Transformer Optimal Protection using Internet of Things

In power system transmission and distribution transformers plays crucial role. As per the consumer requirement the transformers either step up or step down voltages and deliver the power. Sometimes they are operating under overload conditions. In this paper, Microcontroller and different types of sensors can be used to protect the transformer against over load and various internal faults. Real time monitoring of the transformer is also an important part in the transformers protection. A prototype hardware module has designed to sense the temperature raise and pressure in the transformer tank using micro controller based sensors. The monitoring and protection can avoid various faults in the transformer and it can give better performance.
