Abstract

Power transformers reliability, amongst other things, depends on its insulation system. High voltage leads are a part of the insulation system and should be properly insulated. This includes positioning an insulation barrier between the leads and a tank on a certain distance. This distance affects the safety factors (breakdown probability) for such system. The paper presents optimization process with which both the breakdown probability and leads vs. tank distance could be minimized. It also proposes a method with which this optimization process could be confirmed.
