Therefore, timely detection of partial discharge in switchgear and potential insulation faults is an urgent problem that needs to be addressed in the power supervision industry. In this study, a device was proposed for online monitoring of high-voltage switchgears based on pulse current method and ozone (O<jats:sub>3<\/jats:sub>) detection. The pulse current method obtains the PD signal by monitoring the phase holes on the switch indicator. Occurrence of a partial discharge in a certain phase leads to the production of a discharge pulse, which can be coupled out by a capacitive sensor. The current spectrum and the O<jats:sub>3<\/jats:sub> produced by partial discharge were processed via fast Fourier transform for accurate diagnosis of the occurrence of partial discharge and its severity in switchgears. The proposed method allows for convenient acquisition of the partial discharge signal, simple installation of the device, and realization with inexpensive sensors. <\/jats:p>","DOI":"10.1177\/1550147721999284","type":"journal-article","created":{"date-parts":[[2021,2,27]],"date-time":"2021-02-27T04:44:35Z","timestamp":1614401075000},"page":"155014772199928","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Device for online monitoring of insulation faults in high-voltage switchgears"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3906-7961","authenticated-orcid":false,"given":"Jiajia","family":"Song","sequence":"first","affiliation":[{"name":"College of IoT Engineering, Hohai University, Changzhou, China"},{"name":"Jiangsu Key Laboratory of Power Transmission and Distribution Equipment Technology, Changzhou, China"}]},{"given":"Jinbo","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of IoT Engineering, Hohai University, Changzhou, China"},{"name":"Jiangsu Key Laboratory of Power Transmission and Distribution Equipment Technology, Changzhou, China"}]},{"given":"Xinnan","family":"Fan","sequence":"additional","affiliation":[{"name":"College of IoT Engineering, Hohai University, Changzhou, China"},{"name":"Jiangsu Key Laboratory of Power Transmission and Distribution Equipment Technology, Changzhou, China"}]}],"member":"179","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"issue":"35","key":"bibr1-1550147721999284","first-page":"119","volume":"13","author":"Bing C.","year":"2015","journal-title":"Sci Technol Cap"},{"key":"bibr2-1550147721999284","doi-asserted-by":"publisher","DOI":"10.3390\/en12234543"},{"key":"bibr3-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1515\/pac-2017-0312"},{"issue":"2","key":"bibr4-1550147721999284","volume":"38","author":"He S","year":"2015","journal-title":"Electromech Technol Hydropow Stat"},{"key":"bibr5-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1109\/TDEI.2019.008176"},{"key":"bibr6-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1109\/TIA.2018.2874875"},{"key":"bibr7-1550147721999284","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/AMM.448-453.2011"},{"key":"bibr8-1550147721999284","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/AMM.448-453.3485"},{"key":"bibr9-1550147721999284","volume-title":"Study on load characteristics and high frequency discharge power supply of DBD O3 generator","author":"Huang Y.","year":"2005"},{"issue":"11","key":"bibr10-1550147721999284","first-page":"282","volume":"63","author":"Li D","year":"2014","journal-title":"J Phys"},{"key":"bibr11-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1109\/TDEI.2013.6518948"},{"key":"bibr12-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1109\/TDEI.2015.004828"},{"key":"bibr13-1550147721999284","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRD.2016.2635382"},{"key":"bibr14-1550147721999284","volume-title":"IEC 60270: high-voltage test techniques: partial discharge measurements","author":"International Electrotechnical Commission","year":"2015"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1550147721999284","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1550147721999284","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1550147721999284","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,2,27]],"date-time":"2021-02-27T04:44:41Z","timestamp":1614401081000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1177\/1550147721999284"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,2]]},"references-count":14,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2021,2]]}},"alternative-id":["10.1177\/1550147721999284"],"URL":"https:\/\/doi.org\/10.1177\/1550147721999284","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"value":"1550-1477","type":"print"},{"value":"1550-1477","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,2]]}}}
