Abstract :
Ultra high frequency electromagnetic wave in GHz region was investigated for partial discharge detection of model sample of inverter-fed motors during short rise time repetitive impulses. Both ultra wide band and narrow band antenna shows sensitive PD detection ability compared with optical detection which is immune to electromagnetic disturbance.
