Accurate modeling and analysis of the dc cable terminal (CT)—a power device with insulating dielectrics in solid, liquid, and gas states—are crucial for preventing fault formation. Based on the thermal-assisted/variable-range hopping conductance model of cross-linked polyethylene (XLPE), this study identifies the electric field reversal phenomenon in the radial section of XLPE under various conditions. By using different position parameters and operating parameters as independent variables for electric field intensity fitting, we enhance the efficiency of accurately obtaining the internal electric field intensity during the dc CT operation. The analytical results show that the internal electric field is most uniform when an appropriate load is applied to the conductor, representing the healthiest operating mode for the dc CT. This study provides a reference for determining the internal insulation state of the CT under different operating conditions, enabling early detection of potential issues and the adoption of corresponding countermeasures.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 4","pages":"2366-2374"},"PeriodicalIF":3.1,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic principle of the RMP method is introduced in detail. Meanwhile, a corresponding experimental platform is built, and the surface charge distribution results obtained by the RMP method are compared with those obtained by the traditional multipoint measurement (TMM) method. The results show that for the ring-shaped measuring points’ set in this article, the RMP method can detect the surface charge accumulation on about 1/3 area of the insulator surface, and the surface charge density value obtained by the RMP method is approximately equal to the sum of the surface charge density contribution value on the subelement in this region (which is equal to the surface charge density multiplied by the contribution coefficient ratio). In addition, the square root of peak mean square error (PMSE) for the RMP method performed best at 24 measuring points, with a mean error of 11.7%. This study can provide a reference for the surface charge measurement technology of dc GIL insulators.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 4","pages":"2134-2142"},"PeriodicalIF":3.1,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response, a PD test method is suggested with X-ray irradiation. To verify its effectiveness, the discharge characteristics of bush-type electrical tree samples at different degradation stages were systematically measured under X-ray irradiation. Experimental results demonstrate that X-ray irradiation exhibits an excitation effect on electrical tree PD at all stages except the first stage (S1). Specifically, during the second stage (S2), X-ray irradiation amplified the maximum discharge magnitude (<inline-formula> <tex-math>${Q}_{max }$ </tex-math></inline-formula>) by 17.17 times, and the maximum pulse repetition rate (PRRmax) by 2.6 times. For the third stage (S3), X-ray irradiation increases <inline-formula> <tex-math>${Q}_{max }$ </tex-math></inline-formula> by 4.1 times and PRRmax by 2.5 times. For stage 4.1 (S4.1), X-ray irradiation increased <inline-formula> <tex-math>${Q}_{max }$ </tex-math></inline-formula> by 3.1 times, and PRRmax was greatly increased. For stage 4.2 (S4.2), X-ray irradiation can excite the stopped discharge. X-ray provides initial electrons for PD by ionizing gas in electrical trees to maintain the streamer propagation and reduce the statistical delay of PD. This research can provide a new method for PD detection of epoxy resin electrical tree defects.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 4","pages":"2122-2133"},"PeriodicalIF":3.1,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
