Initially regarded as exotic materials, they have since evolved into widely accessible advanced materials. Research has primarily focused on solid polymer nanocomposites and has recently expanded to include liquid nanocomposites, known as nanofluids. Over the past decade, considerable progress has been made in the field of nanodielectrics. To capture this progress, more than 400 papers published in the IEEE Transactions on Dielectrics and Electrical Insulation and IEEE Electrical Insulation Magazine between 2011 and 2023 have been collected and reviewed. The evaluation of host materials, guest nanoparticles, and their combinations has been carried out to identify those that deliver superior performance. Notable advances in microscopic studies of interphases and particle dispersions are highlighted. Applications in high-voltage (HV) equipment and power electronics devices are also referenced to promote further research in this area. In addition, it is important to recognize that machine learning (ML) plays a critical role in accelerating the research and development of nanodielectrics and their applications.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 1","pages":"102-116"},"PeriodicalIF":2.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106397","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}

It is difficult to further analyze the cause and mechanism of faults, which could provide little help for the maintenance and optimization design of HVCBs. To address this problem, a fault feature assessment method of HVCBs based on explainable image recognition is proposed to realize a quantitative analysis of faults. First, the vibration signals of HVCBs are preprocessed by continuous wavelet transform (CWT). The time-frequency diagrams of CWT are segmented by the travel curve to obtain the action sequence of the HVCB. Then, Shapley additive explanations (SHAPs) explain the deep residual network ResNet to obtain the feature importance distribution maps. Through the feature importance distribution map, accurate fault location and time traceability can be realized, and the frequency-domain features of the fault can be directly visualized from the distribution degree of the feature importance. The fault evaluation factor (FEF) is proposed to quantitatively study the time-frequency–amplitude comprehensive difference between the fault state and the normal state of the circuit breaker.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 1","pages":"92-101"},"PeriodicalIF":2.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106323","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}

Despite this attention, the evaluation of the properties of polymer-based composite components, both as part of post-manufacturing control and in-service checks, remains challenging. In this article, ultrasonic testing is investigated as a nondestructive approach for the quality evaluation of high-voltage composite insulators. Classical phase array ultrasonic testing is compared with the total focusing method. The results are validated using computed tomography and a destructive testing approach. It was demonstrated that the proposed ultrasonic testing (UT) technique detected microcracks and small voids in the analyzed samples similar to the reference testing approaches. It was also proved that the water immersion total focusing method can be successfully implemented in a full-scale production process if the scanning and data analysis tasks are properly automated. Since the pilot solution was developed to evaluate objects with relatively simple shapes, further work is needed to cope with more complex geometries.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 1","pages":"83-91"},"PeriodicalIF":2.9,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106455","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 amplitude of the overvoltages in the windings is dependent on the parameters of the surge voltage (duration, waveform, steepness, etc.) and the design of the windings, thus various winding designs perform differently when surge voltage is applied to their terminals. The transformer winding vulnerability to surge phenomena can be estimated based on the initial voltage distribution. In practice, the initial voltage distribution can be improved by increasing the series or decreasing the ground capacitance of the winding, by design changes, or by application of electrostatic shields. This article presents the analysis of the initial voltage distributions in power transformer windings, comparing layer and disk designs. The analysis was done based on the results of measurements of surge voltage waveforms in real-scale winding models, while a lightning impulse is applied to their terminals. The experimental analysis was extended by simulations of the electrostatic potential distribution in the winding models, and the influence of selected factors (shielding, interleaving turns) on the initial voltage distribution was analyzed and discussed. The article is focused on the comparison of initial voltage distribution in transformer windings of disk and layer designs based on quantitative and qualitative analysis.","PeriodicalId":13247,"journal":{"name":"IEEE Transactions on Dielectrics and Electrical Insulation","volume":"32 1","pages":"73-82"},"PeriodicalIF":2.9,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106322","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 this article, wavelength division multiplexing (WDM) and cavity ring-down spectroscopy (CRDS) were combined to achieve the synchronous and accurate detection of H2S/CO2, which was executed by multiplexing the optical paths of two distributed feedback (DFB) lasers in the 1578/1600 nm wavelength band. To avoid instrument redundancy, a self-developed high-precision laser diode controller (LDC) board was implemented for the current and temperature modulation of dual-laser.
