An ultrawideband patch antenna for UHF detection of partial discharge
2015
The location of partial discharge (PD) sources by free-space UHF detection is an attractive approach for condition monitoring of high voltage equipment in substations. A low-cost, radiometric, PD wireless sensor network (WSN) has been proposed to provide continuous real-time coverage for an entire substation (J.M. Neto, Y. Zhang, A. Jaber, M. Zhu, M. Judd, R. Atkinson, J. Soraghan, J.S. Neto, M.F. Vieira, I.A. Glover, 2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), Beijing, 16 – 23 Aug. 2014, pp.1–4). A suggested band for UHF PD detection is 0.3 – 1.5 GHz (Z. Tang, C. Li, X. Cheng, W. Wang, J. Li, IEEE Trans. Dielectr. Electr. Insul., 6, 2006, pp. 1193–1199). A novel ultrawideband (UWB) printed monopole antenna is presented here for PD WSN applications.
