Aging of oil-impregnated transformer insulation studied through partial discharge analysis
Conference paper - X Chen, P.H.F. Morshuis, Q. Zhuang, J.J. Smit, Z Xu
The aging of the epoxy-paper insulation of an oil-impregnated transformer was studied through partial discharge analysis. Accelerated electrical aging tests were carried out on samples of transformers windings, with and without paper insulation. Partial discharge (PD) measurement ...

Life prediction for epoxy resin insulated transformer windings through accelerated aging tests
This investigation aims to perform a probabilistic prediction of the lifetime of epoxy resin insulation of transformer windings. To support the prediction, several accelerated electrical aging tests were conducted at different voltage levels on epoxy resin insulated transformer w ...
