However, extracting weak discharge signals from strong disturbances is a significant challenge. The presence of noise can hamper the identification and localization of PD types, making the extraction of pure PD signals the focus of current research. This paper proposes a PRPD-based PD filtering algorithm that analyzes interference using the output information from PRPD and sets threshold parameters for noise reduction processing. This method is mainly used for secondary noise reduction at a later stage, without analyzing the noise source, to achieve effective signal acquisition while retaining the characteristics of the PD signals, thereby improving the system\u2019s sensitivity and the signal\u2019s purity.<\/jats:p>","DOI":"10.3390\/s23156763","type":"journal-article","created":{"date-parts":[[2023,7,31]],"date-time":"2023-07-31T02:13:32Z","timestamp":1690769612000},"page":"6763","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A PRPD-Based UHF Filtering and Noise Reduction Algorithm for GIS Partial Discharge"],"prefix":"10.3390","volume":"23","author":[{"given":"Weixing","family":"Fang","sequence":"first","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Hangzhou Kelin Electric Co., Ltd., Hangzhou 310011, China"}]},{"given":"Guojin","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Anji Intelligent Manufacturing Technology Research Institute Co., Ltd., Hangzhou Dianzi University, Huzhou 313000, China"}]},{"given":"Wenxin","family":"Li","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Anji Intelligent Manufacturing Technology Research Institute Co., Ltd., Hangzhou Dianzi University, Huzhou 313000, China"}]},{"given":"Ming","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"},{"name":"Anji Intelligent Manufacturing Technology Research Institute Co., Ltd., Hangzhou Dianzi University, Huzhou 313000, China"}]},{"given":"Wei","family":"Xie","sequence":"additional","affiliation":[{"name":"Hangzhou Kelin Electric Co., Ltd., Hangzhou 310011, China"}]},{"given":"Chang","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Wanqiang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"}]},{"given":"Yucheng","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"158","DOI":"10.1049\/hve2.12127","article-title":"Defects and failure types of solid insulation in gas-insulated switchgear: In situ study and case analysis","volume":"7","author":"Xing","year":"2021","journal-title":"High Volt."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1109\/MEI.2004.1307097","article-title":"Electrical insulation for rotating machines-design, evaluation, aging, testing, and repair\u2014Book Review","volume":"20","author":"Stone","year":"2004","journal-title":"IEEE Electr.
