Distribution transformers are one of the most important equipment in power system. Hence it's monitoring plays a vital role. Four parameters are chosen to monitor the health of distribution transformer. They are temperature of transformer, voltage and current, oil level and dissolve gases. Monitoring and control of transformer is done by using various sensors. RF Communication system is used to send the captured data to control room for necessary controlling initiation. This project present an efficient online method for monitoring and control of distribution transformer through wireless communication.
