GIS bushing Considering the fact that electrical electrical power may be the item of voltage and recent, insulation within a bushing needs to be effective at withstanding the voltage at which it is actually used, and its current-carrying conductor has to be capable of carrying rated present with no overheating the adjacent insulation.
In a very solid insulation product, partial discharges allow the defect to propagate from the insulation until eventually there is a partial or full breakdown with the insulation. In contrast, in a very bushing with liquid insulation convective move from the oil due to distinct oil temperatures helps to dislocate the defect inside the bushing in a ‘self-therapeutic’ method.
