Online Monitoring and Controlling of Transformer Parameters Using Wireless System

摘要

Transformers are used to provide power transmission by transforming induced current from one circuit to another. The induced current can be converted from step up or step down of current or voltage. Project is focused on the three phase transformers which are used in between electric poles and the power transformers. The real time monitoring and controlling of transformer parameters like gas level, oil aging and temperature, overload regulation and maintenance is implemented. These parameters are essential for effective power transmission and long life of industrial power transformers. The monitoring and controlling unit has been built around PIC16F877A microcontroller with RF transmission module, gas and oil level sensors, temperature sensor etc. There are various conventional transformer maintenance techniques but this paper gives a real time monitoring and controlling of transformers by using microcontroller which replace the bulky computers making it as embedded system. So, this system makes possible to attain real time controlling and monitoring of above mentioned parameters.
