Abstract

We have investigated characteristics of varnish and oil impregnant. When transformers are manufactured with some moisture and varnish impregnant not entirely dried, those should be caused by factors that deteriorate the electrical or mechanical property after installation. Therefore, in this study we experienced moisture content of the new insulating paper and the varnish impregnant paper in the ratio of time for confirming factors that deteriorate the paper characteristics. Besides, we investigated a property study that was experienced the value of dielectric strength and tensile strength as no serviced insulating samples of transformer.
