Partial Discharge Measurements for Quality in High Assessment of Insulation Systems Voltage Electrical Machinery

Abslroa In this paper, we present B new statistical analysis method of phase resolved partial discharge (PD) measurements for the quality assessment o f the electrical insulation in high voltage machinery. The method is based on P supervised classification approach which utilizes histogram similarily analysis. The motivntian for choosing histogram similarily analysis is huofold: F i r s t the p...

Partial Discharge Measurements on Glass-mica-epoxy Samples for Electrical Insulation during Accelerated Thermo-oxidative Aging

The stator windings of large air-cooled rotating machines are mainly insulated with mica-glass fabric impregnated with epoxy resin. In service, these materials are submitted to thermal, mechanical and electrical stresses. A specific aging arrangement has been set-up allowing artificial thermo-oxidative aging of samples, thanks to the application of a dry O2 pressure at a controlled temperature....
