Based on the multi-grade surge protector and new grounding technology, through the impulse experiments, we apply simulated lightning current generated from combined wave generator (1.2\/50 \u03bcs, 8\/20 \u03bcs) on the modle, and an oscilloscope is used to collect residual voltage and current data to calculate the absorbed energy of the grounding unit. It is concluded that when the impulse voltage is between 300\u00a0V and 3500 V, as the impulse voltage increases, after passing through the multi-grade surge protector and grounding unit, the residual voltage and current value continue to increase, and the residual voltage value is 23.4 V\u201329.6 V increases linearly, and the increase is small; the internal resistance of the grounding unit decreases with the increase of the impulse voltage. The energy absorbed by the grounding unit is positively correlated with the impulse voltage and negatively correlated with the internal resistance, and its energy absorption percentage decays linearly. The multi-grade surge protector can effectively clamp the residual voltage value within a safe value, and its discharge effect is better than that of the traditional protection mode. It provides a theoretical basis and data reference for the lightning protection and anti-interference projects of the actual transmission tower sharing equipment, and has certain practical value.<\/jats:p>","DOI":"10.3233\/jcm-226682","type":"journal-article","created":{"date-parts":[[2023,1,31]],"date-time":"2023-01-31T11:44:09Z","timestamp":1675165449000},"page":"1197-1207","source":"Crossref","is-referenced-by-count":1,"title":["Lightning protection technology and grounding technology of transmission tower shared equipment"],"prefix":"10.1177","volume":"23","author":[{"given":"Liang","family":"Hong","sequence":"first","affiliation":[{"name":"State Grid Fujian Electric Power Co., Ltd., Fuzhou, Fujian, China"}]},{"given":"Kaibin","family":"Wu","sequence":"additional","affiliation":[{"name":"Wuhan Efficiency Evaluation Co., Ltd., State Grid Electric Power Research Institute, Wuhan, Hubei, China"},{"name":"NARI Group Co., Ltd., State Grid Electric Power Research Institute Co., Ltd., Nanjing, Jiangsu, China"}]},{"given":"Mengmeng","family":"Yue","sequence":"additional","affiliation":[{"name":"Wuhan Efficiency Evaluation Co., Ltd., State Grid Electric Power Research Institute, Wuhan, Hubei, China"},{"name":"NARI Group Co., Ltd., State Grid Electric Power Research Institute Co., Ltd., Nanjing, Jiangsu, China"}]}],"member":"179","reference":[{"issue":"7","key":"10.3233\/JCM-226682_ref3","first-page":"110","article-title":"Three-dimensional reconstruction of transmission tower based on multi-source data fusion","volume":"41","author":"Ding","year":"2022","journal-title":"Auto Technol Appl."},{"issue":"3","key":"10.3233\/JCM-226682_ref4","first-page":"68","article-title":"The influence of soil resistivity frequency-dependent characteristics on the induced voltage of buried pipelines when lightning strikes transmission towers","author":"Kou","year":"2022","journal-title":"Electr Porcelain Arrester."},{"issue":"5","key":"10.3233\/JCM-226682_ref5","first-page":"41","article-title":"An efficient calculation method of electric field around AC transmission tower using matrix compression technology","volume":"58","author":"Yang","year":"2022","journal-title":"High Vol Electr Apparatus."},{"issue":"4","key":"10.3233\/JCM-226682_ref6","first-page":"105","article-title":"Research progress on structural reliability of transmission towers in China","volume":"20","author":"Chen","year":"2022","journal-title":"Tech Inf."},{"issue":"1","key":"10.3233\/JCM-226682_ref7","first-page":"240","article-title":"Research on operation state monitoring and LSD algorithm of transmission tower based on anti-icing flashover","volume":"12","author":"Qu","year":"2022","journal-title":"Mod Ind Econ Inf."},{"issue":"1","key":"10.3233\/JCM-226682_ref8","first-page":"61","article-title":"Abnormal vibration identification of transmission towers in complex environments based on transfer learning","volume":"20","author":"Zhang","year":"2022","journal-title":"Power Inf Commun Technol."},{"issue":"5","key":"10.3233\/JCM-226682_ref9","first-page":"107","article-title":"Transient overvoltage modeling and analysis of transmission tower and grounding system based on EMTP","author":"Li","year":"2021","journal-title":"Electr Porcelain Arrester."},{"issue":"3","key":"10.3233\/JCM-226682_ref10","first-page":"60","article-title":"On-line monitoring of transmission line tower settlement in coal mine goaf based on laser ranging method","volume":"35","author":"Zhao","year":"2021","journal-title":"J Xi\u2019an Polytech Univ."},{"issue":"4","key":"10.3233\/JCM-226682_ref11","first-page":"128","article-title":"Lightning protection and grounding technology of substation","author":"Wang","year":"2022","journal-title":"Energy Energy Sav."},{"issue":"24","key":"10.3233\/JCM-226682_ref12","first-page":"65","article-title":"Application of lightning protection and grounding technology in cable TV system","volume":"10","author":"Zhang","year":"2018","journal-title":"Technol Commun."}],"container-title":["Journal of Computational Methods in Sciences and Engineering"],"original-title":[],"link":[{"URL":"https:\/\/content.iospress.com\/download?id=10.3233\/JCM-226682","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T16:32:30Z","timestamp":1771000350000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.3233\/JCM-226682"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,30]]},"references-count":10,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.3233\/jcm-226682","relation":{},"ISSN":["1472-7978","1875-8983"],"issn-type":[{"value":"1472-7978","type":"print"},{"value":"1875-8983","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,5,30]]}}}
