Fabry-Perot (F-P) sensors are capable of detecting PD acoustic signals. Although the frequency bandwidth of an F-P sensor is mainly referred to conventional piezoelectric transducer (PZT) sensor, it is still doubtful to identify a suitable bandwidth for fiber sensors in detection of PD signals. To achieve a suitable bandwidth for an F-P sensor, the frequency distribution of PD acoustic emission is investigated, and an extrinsic F-P sensor is designed to detect acoustic signals generated from PD. F-P sensors with different intrinsic frequencies are fabricated as possible design standards of bandwidth for acoustic detection. PD acoustic signals are detected by these F-P sensors and PZT sensors in the experimental system, in which four typical electrode models are employed. The measured results of frequency performance are analyzed in linear and semilogarithmic coordinates. The results show that F-P sensors can effectively detect PD acoustic emissions in both wideband and narrowband modes. Moreover, F-P sensors achieve a higher sensitivity in the narrowband mode. We propose that intrinsic frequency of the F-P sensor should be designed in the frequency range of 100\u2013170\u2009kHz to obtain maximum sensitivity.<\/jats:p>","DOI":"10.1155\/2019\/1026934","type":"journal-article","created":{"date-parts":[[2019,11,18]],"date-time":"2019-11-18T18:30:22Z","timestamp":1574101822000},"page":"1-11","source":"Crossref","is-referenced-by-count":18,"title":["Response Bandwidth Design of Fabry-Perot Sensors for Partial Discharge Detection Based on Frequency Analysis"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3174-9597","authenticated-orcid":true,"given":"Qi-Chao","family":"Chen","sequence":"first","affiliation":[{"name":"Key Laboratory of Engineering Dielectrics and Its Application, Ministry of Education, School of Electrical and Electronic Engineering, Harbin University of Science and Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2503-582X","authenticated-orcid":true,"given":"Wei-Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Engineering Dielectrics and Its Application, Ministry of Education, School of Electrical and Electronic Engineering, Harbin University of Science and Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0979-4073","authenticated-orcid":true,"given":"Hong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Engineering Dielectrics and Its Application, Ministry of Education, School of Electrical and Electronic Engineering, Harbin University of Science and Technology, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1049\/iet-smt.2018.5092"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.3390\/s140407451"},{"issue":"6","key":"3","first-page":"573","volume":"1","year":"2017","journal-title":"Current Optics and Photonics"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2016.2526644"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/JLT.2006.875955"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-3992(01)00022-6"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1088\/0960-1317\/15\/3\/012"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/LPT.2015.2506480"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/JMEMS.2012.2196494"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1364\/OE.26.011025"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.optlastec.2018.07.055"},{"first-page":"9","volume-title":"IEEE guide for the detection and location of acoustic emissions from partial discharges in oil-immersed power transformers and reactors","year":"2007","key":"12"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1364\/ao.42.003241"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/57.145095"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/94.946712"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-7796(02)00091-3"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1026934.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1026934.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1026934.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,18]],"date-time":"2019-11-18T18:30:25Z","timestamp":1574101825000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2019\/1026934\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,18]]},"references-count":16,"alternative-id":["1026934","1026934"],"URL":"https:\/\/doi.org\/10.1155\/2019\/1026934","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2019,11,18]]}}}
