Abstract :
Dielectric liquids have been used as an insulator for more than a century. The initiation of electrical breakdown and the role various types of effects have on it have been investigated for the last 30-40 years. In this study the variation of the breakdown voltage of transformer oil chosen as a liquid insulator with both electrode shape and gap has been examined. For this purpose, homogeneous and inhomogeneous fields with 5 pairs of electrodes which are at different standards have been created. The effects on electrical breakdown voltage of moisture content in the oil have also been investigated
