This research aims at assessing the severity level of typical cable local ageing defects based on the high-voltage frequency domain spectroscopy (FDS) non-linearity. Experimentally, typical XLPE cables ageing defect conditions are simulated, with different ageing types, degrees, and local proportions. Then, the high-voltage FDS detection is conducted and the results have been analysed. It has been found that the high-voltage FDS non-linearity is only related to the detection voltage and ageing degree. Especially, it is more sensitive to changes in the ageing severity. Thus, the local ageing defect severity assessment method based on non-linearity has been established. Additionally, the sensitivity has been compared between two diagnostic evaluation methods: the high-voltage FDS and the widely used very-low frequency method (VLF, 0.1 Hz). It can be concluded from the comparison result that the proposed assessment method has higher sensitivity than that of the traditional methods. Finally, the effectiveness of the proposed method for evaluating the on-site long cables has been validated. The result demonstrates that the proposed method can assess on-site long cables and has the potential to be formed as quantitative standards.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 2","pages":"385-399"},"PeriodicalIF":4.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.12518","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temperature variations and abnormal distributions can signal potential equipment failures that threaten system stability. Therefore, monitoring these critical multi-point temperature variations is essential. However, the unique design of the bushings, featuring insulation sheds of periodic shape, distorts infrared temperature measurements by introducing interference points. These interference points, dependent on the measurement's angle and distance, appear irregularly in infrared images, severely impacting the accuracy of multi-point temperature distribution assessments. To address this challenge, an anomaly detection method is proposed that adaptively identifies interference points. The method identifies interference points by comparing pixels and uses a voting mechanism to improve identification accuracy. Compared with traditional methods, this approach presents two main advantages: adaptive identification capability, which enables it to recognise interference points and adapt to changing conditions, and unsupervised learning, which enables it to work effectively without requiring manually labelled data. Experimental tests on 161 bushing infrared images demonstrate the effectiveness of the method, achieving a 100% success rate in identifying localised overheating issues. The method has been integrated into high-voltage direct current transmission anomaly systems and can be used to monitor critical equipment, enhancing system reliability and safety.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 2","pages":"411-418"},"PeriodicalIF":4.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.70007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the exploration of SH characteristics concerning single-layer dielectric film remains insufficient for advancing MFC reliability evaluation. To establish the theoretical correlation of SH characteristics from the device to the film in the MFCs, this work developed a simulation model to analyse the SH dynamic behaviour in the MFCs. The effects of coupling capacitors, arc resistance and insulation resistance on the macroscopic characteristics (voltage drop and pulse current) are focused during the SH process in MFCs. The results indicate that SH is primarily associated with the voltage drop duration rather than the sampling current. Consequently, the SH process in MFC is characterised as an abrupt decrease in voltage to its minimum value. This refinement enhances the SH energy dissipation model of MFC. The quantified relationship between the macroscopic characteristics and microstructure evolution (polypropylene decomposition and aluminium electrode vaporisation) is established in MFCs under diverse SH energy levels. As SH energy and duration increase, the proportion of energy attributed to polypropylene decomposition increases, resulting in multi-layer ablation and adhesion within the metallised film and a pronounced deterioration in MFC electrical performance. The examination of macro–micro perspectives sheds new light on the intricate mechanisms governing the SH behaviour in MFCs, offering valuable insights for the advancement of their design, reliability evaluation, and performance optimisation in diverse electrical applications.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 2","pages":"362-373"},"PeriodicalIF":4.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples are prepared using PP and styrene–ethylene–butylene–styrene elastomer with contents ranging from 0 wt% to 50 wt%, and exposed to Cobalt-60 gamma irradiation, with a dose from 0 to 250 kGy. Electrical conductivities at different temperatures and trap distributions are measured to observe the deterioration of insulation performance. The microstructure of the sample is estimated using differential scanning calorimetry, X-ray diffraction, thermogravimetric analysis and a scanning electron microscope. The obtained results demonstrate a correlation between the increase in electrical conductivity and the elevation in both total dose and temperature. At 250 kGy, the trap distribution tends to become shallower, accompanied by a decrease in crystallinity, melting and decomposition temperatures of the sample. The PP composite exhibits better stability against irradiation and thermal effects, primarily due to the cross-linked structures formed by irradiation.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 2","pages":"470-479"},"PeriodicalIF":4.4,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work also experimentally studies the electrical characteristics of the gas medium and the monitored parameters are also used to calibrate the arc model. The amount change of the seven dominant decomposing by-products is analysed as well. The results present that the C4F7N/CO2/O2 ternary gas mixture exhibits a more promising interrupting performance. Increasing the O2 concentration from 5% to 10% has less effects on the arc characteristics, but it could suppress the formation of CO. The arc behaviour of C4F7N/CO2/O2 gas mixture is also improved with increasing the velocity of the moving components.

In this paper, the new characteristics that arise from the high penetration of IBRs in power systems are reviewed. In light of these characteristics, current simulation technologies are inadequate and new requirements for the simulation platforms have been proposed. In response, this paper introduces the rapid system prototype (RSP)-based physical simulation platforms, which include the digital simulator, the rapid prototype controller, and the rapid object-controlled prototype. RSP addresses the time-consuming and labour-intensive shortcomings of traditional simulation techniques and meets the rapid evolution needs of the power system with high penetration of IBRs. Compared with existing simulation platforms, RSP is a more suitable platform for the physical simulation of power systems with high penetration of IBRs. Using the modular multilevel converter-based high-voltage direct current as a case study, a novel physical simulation platform for power systems based on RSP is constructed. Experimental results demonstrate that the RSP concept and technology can establish an enterprise-level simulation environment and engineering practice platform. Moreover, it can provide realistic and flexible simulations of various characteristics of power systems with high penetration of IBRs.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 1","pages":"3-16"},"PeriodicalIF":4.4,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.12520","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
