Abstract

We studied the partial discharge detecting by sensing electromagnetic pulse emitted from the partial discharge source in the stator winding of HV Rotating Machine with UWB sensor. In this study, we designed new type of compact low frequency UWB sensor based on micro-strip technology and made experiments of offline dismantled testing compare with the traditional HFCT as a reference sensor in the laboratory. We investigated internal discharge, surface discharge, corona discharge and non-defected state normal stator on pre-made stator winding by using UWB patch sensor.
