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}

A modified theoretical basis of the arc model developed for the C4F7N-based gas mixture is presented in the work with particular emphasis on the non-recombination features of C4F7N. 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. The findings provide important insights into the potential of C4F7N-based gas mixtures as one of the sustainable and effective solutions for high-voltage interrupting applications.","PeriodicalId":48649,"journal":{"name":"High Voltage","volume":"10 1","pages":"228-242"},"PeriodicalIF":4.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/hve2.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533999","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}

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}

In the experiment, naphthenic mineral oil was chosen as the base fluid. MgO, Al2O3, and SiO2 were preferred as nanoparticles. In the dielectric breakdown voltage (BDV) tests performed, increased values were observed at certain concentrations for each nanofluid, with the highest value in the SiO2-based nanofluid being 83.47 kV at a concentration rate of 0.05 g/L. Adding nanoparticles to the base oil increased the viscosity of all suspensions. Except for MgO-based dielectric nanofluid, the flash points of other nanofluids increased as compared to pure oil. Total acid number (TAN) values, on the other hand, increased for SiO2- and Al2O3-based nanofluids but decreased for MgO-based nanofluids. However, all values are quite below the standard limit of 0.25 mgKOH/g. The percentage transmittance values calculated from the ultraviolet and visible light (UV–vis) spectrophotometry results differed for each nanofluid. However, they were all lower than the base oil.

The results show that MAH grafting can significantly reduce the volume resistivity of semi-conductive composites, especially at a higher temperature, to suppress the PTC effect.
