Online diagnostic ultra-wideband antenna system in high voltage polymeric insulator
Paper i proceeding, 2019

A novel ultra-wideband (UWB) antenna system is proposed for fault inspection and online diagnoses on high voltage polymeric insulators. This technique makes use of the multimode transferring theory on dielectric waveguides, where the transmission signal level difference can be employed to detect internal defects in the core rod. An investigation by simulation is performed with regard to the interfacial mm-ordered cracks in transverse and longitudinal orientations, and roughly 30~50 dB and 20~40 dB differences have been observed over the same band 3~10 GHz, respectively.
