Fundamentals of condenser bushings
K.K. Murty
Abstract
This article focuses on the concept of capacitance-graded, i.e. condenser bushings – both oil-impregnated and resin-impregnated paper bushings – for extra-high voltage transformers. After a description of the dielectric loss, the article goes on to describe the selection, testing, transportation, storage and installation of these bushings, so as to avoid a bushing failure which may lead to a catastrophic failure of transformers.
Keywords
