Abstract :
The dielectric performance of insulating oils used in high voltage equipment is very important for the power system continuity and reliability. In this study, breakdown voltage measurements of mineral insulating oil were carried at different temperatures and water quantity rates were researched. Additionally, the effect of water content inside the oil sample, approximately 2.5 percent, on the breakdown voltage was analyzed for particular temperatures. In the experimental study, the breakdown voltage behavior of mineral oil which is widely used in power transformers was acquired according to the ASTM D877 standard for different service conditions and the obtained results were presented.
