Condition Monitoring of Transformer through PC, Internet (Cloud)

Abstract — The propose is an innovative design to develop a system based on Arduino ProATmega168 microcontroller that is used for monitoring the voltage, current, temperature, frequency, vibration of a HV transformer in a Lab and to protect the system from the rise in above mention parameters. This project capable of recognizing the breakdown caused due to Temperature rise, over voltage and current. The design generally consists of two units, one in the substation unit, called as transmitter and display unit in main station called as controlling unit. Transmitter and display unit in the substation is where the parameters are monitored continuously by ATmega168 microcontroller and is displayed through display unit. The controlling unit in the main station by means of PC and receives the signal through cloud (Wi-Fi, LAN, INTERNET), and reacts in accordance to the received signal. In general, the proposed design is developed for the user easily recognized the distribution transformer that is suffered by any fault. The ultimate objective is to monitor the electrical parameters continuously and hence to guard the burning of distribution transformer or power transformer due to the constraints such as over load, over temperature and input high voltage. Analysis of transformer parameter through PC, and cloud is an advance concept with a number of unique features including early detection and self-healing capabilities. An implementation of this project can monitor as well as measure data for protection. Apparent benefits from the project are robust and reliable system
