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

PD measurement is a worldwide-accepted method for insulation diagnosis and a required part of the acceptance testing for many HV assets. To facilitate PD measurements different
techniques/methods have been developed and they are in use for laboratory and on-site applications. All

Since the early nineties, ultra-high-frequency (UHF) partial discharge (PD) measurements are being applied to SF6 gas-insulated equipment. Over the years, PD measurements revealed the presence of some insulation defects in the 380 kV GIS. The measuring results have been compared
