IOT Based Transformer Parameter Monitoring System Using PICO Microcontroller
Abstract
In this project we are going to monitor temperature of transformer and oil level so that we can find use of transform. This is based on IOT for remotely monitoring of project switching of capacitor bank, reactor and transmission lines are essential in power system, but it creates transient over voltages during switching. These over voltage magnitudes can be controlled by opening or closing of circuit breaker at proper instant of AC wave. Controlled switching solutions are also called point on wave (POW) switching. Opening or closing of circuit breaker at required instant of AC wave can be possible, if Controller operation and circuit breaker operation synchronized to each other. Controller is an intelligent electronic device (IED) based equipment, so its operation accuracy is very high, but circuit breaker is electromechanical device, and its operation depends on various environmental factors as well as parameters like friction between components, gas pressure, and temperature and spring characteristics. One of the challenges in controlled switching application lies in the accurate prediction of the operating time, subject to the various affecting parameters at that instant. The success of controlled switching system depends on the consistency of circuit breaker operating time and reliability of controller to operate in high voltage environment. The work presented in the dissertation focuses on suitability check of the circuit breaker for controlled switching application from mechanical scatter point of view. The allowed circuit breaker scatter for various controlled switching application is discussed in the dissertation along with the system requirement simulation study
