Online Diagnostic High Voltage Polymeric Outdoor Insulation Using Patch Antenna System
Paper i proceeding, 2019

To realize an online diagnosis system for accurate detection of internal defects in high voltage polymeric outdoor insulations, a novel patch antennas system which would detect the transmission signal level difference caused by internal defects of insulations is proposed. In this work, investigation by simulation is performed with regard to the conventional interfacial mm-ordered cracks in both transverse and longitudinal orientations in one kind of insulation, namely insulator. Receiving signal differences of 30-50 dB and 30-60 dB between insulators with and without defects have been observed over 1-10 GHz, respectively to transverse and longitudinal defects. The proposed method by patch antennas system is promising to realize online diagnostic high voltage polymeric outdoor insulations with defects.
