Abstract
It is known that the insulating barrier and electrode coating can hinder the formation of the "impurity bridge" in the oil gap and improve the uniformity of electric field. This paper presents experimental results to show that the dielectric strength of an oil gap is apparently increased by the application of insulating barrier and electrode coating.
