UHF-Printed Monopole Filtenna for Partial Discharge Detection with LTE Signal Suppression [PDF]
Journal of Electromagnetic Engineering and Science, 2023 External partial discharge (PD) sensors for the ultra-high frequency (UHF) method are widely used to detect the PD signals in high-voltage power equipment for ease of installation and maintenance. However, conventional external PD sensors detect not only
