Proper maintenance and testing are essential to ensure their optimal working condition. This study focuses on the CEX series de-excitation switches from LENOIR, France, and develops a multifunctional testing platform capable of measuring contact resistance, testing switch opening and closing, and evaluating synchronous performance. The platform utilizes coordinated control of supercapacitors and loop current control load components to generate a high-quality 1500\u00a0A constant current as the measuring power supply. This significantly reduces the volume of the high-current generation device and improves power density. A shunt and multi-channel synchronous recording module record the action status and time of each switch contact, with a recording accuracy of 0.2\u00a0ms + 0.1%FS, enabling multifunctional testing of the de-excitation switch.<\/jats:p>","DOI":"10.1177\/14727978251320203","type":"journal-article","created":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T02:32:57Z","timestamp":1741833177000},"page":"3875-3884","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Development of a multifunctional testing platform for generator de-excitation switches"],"prefix":"10.66113","volume":"25","author":[{"given":"Jingguang","family":"Yang","sequence":"first","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoxin","family":"Liu","sequence":"additional","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiazhi","family":"Zhang","sequence":"additional","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinsong","family":"Gao","sequence":"additional","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyong","family":"Lv","sequence":"additional","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ju","family":"Zhao","sequence":"additional","affiliation":[{"name":"China Yangtze Power Co., Ltd., Yichang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shusheng","family":"Lin","sequence":"additional","affiliation":[{"name":"eTocsin Inc., Zhuhai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5614-8177","authenticated-orcid":false,"given":"Ruiyu","family":"Zeng","sequence":"additional","affiliation":[{"name":"Jinan University, Zhuhai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huan","family":"Guo","sequence":"additional","affiliation":[{"name":"Jinan University, Zhuhai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"GB\/T7409.3-2007 Excitation system for synchronous electrical machines\u2014technical requirements of excitation system for large and medium synchronous 2007."},{"key":"e_1_3_3_3_2","unstructured":"Xianglong X Junmin F Liuyan Y.
