Abstract:
Power transformers are essential parts of our electric power infrastructure, and transformer components such as bushings and tap changers are essential parts of transformers, ensuring they operate reliably and safely while at the same time minimizing environmental impact.
Bushings are designed for application on liquid filled power transformers and reactors. They are used to connect the power transformer or reactor to overhead lines or exposed bus in either outdoor or indoor conditions.
The objective of this thesis is to implement system to protect and monitor the power transformers high voltage side bushings oil temperature or pressure and to achieve effective electronic circuit to monitoring the oil temperature inside bushings on line.
The oil temperature monitoring system for three phase power transformer bushings will be implement using micro controller based electronic circuit which will send digital signal to mat lab Graphical User Interface (GUI) or using lab view software represent the Human Machine Interface (HMI) .this project will be execute in Rosaries Hydro Power Plant four power transformers bushing (100MVA) each by connected to existing control system Distributed Control System (DCS) as future work.
