Abstract :
We studied the partial discharge detecting by sensing electromagnetic wave emitted from the partial discharge source in the HV Rotating Machine with UWB sensor. In this study, we design new type of compact low frequency UWB sensor based on micro-strip technology and make many experiments of offline and dismantled testing compare with the existing HFCT on stator winding of HV generator in the laboratory. We mentioned detail design of new compact UWB sensor design and time domain and frequency domain results of partial discharge in stator winding of 6.6kV rotating machine by offline testing in laboratory.
