In this paper, a dielectric spectrum testing platform was built to measure the changes of dielectric spectrum of EPR under aging temperature, tensile stress, and different test temperatures, the effects of aging time. and tensile ratio on the dielectric spectrum of EPR were analyzed. The test results show that the real part of the complex dielectric constant and the dielectric loss factor increases exponentially with the increases of the test temperature. With aging time increasing, the real part of the complex dielectric constant increase. and the dielectric loss factor decrease first and then increase. With the increase in tensile ratio, both the real and imaginary parts of the complex dielectric constant decrease first and then increase.","PeriodicalId":125983,"journal":{"name":"2022 IEEE International Conference on High Voltage Engineering and Applications (ICHVE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126678522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Working at high temperature and humidity conditions, oxygen and moisture in atmosphere will permeate into MFCs and initiate electrode corrosion, which contributes to capacitance loss, and thus the reliability is reduced. In this work, a capacitance loss model for atmospheric corrosion is proposed to study the aging pattern of MFCs. Accordingly, an accelerated aging test with different temperature-humidity combinations is carried out to investigate the corrosion behavior at various temperature and humidity conditions. The results indicate the corrosion sites tend to distribute around the fibers on polymer films. The capacitance loss rate declines along time because of formation of oxide layers. It is also found temperature has a predominant effect on corrosion process in contrast of humidity.","PeriodicalId":125983,"journal":{"name":"2022 IEEE International Conference on High Voltage Engineering and Applications (ICHVE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126818953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Random Search optimization is used to find the best wavelet function for matching traces to extract deep features of data. And these extracted deep features are used as complementary inputs to a deep learning model. One-dimension convolutional neural network (1-D CNN) is used to complete the secondary conversion of data features and high-dimensional feature mapping. The data are transformed by dimensionality and bidirectional long and short-term memory network. The data information mining is completed by using the multi-branch structure of the network to filter and merge the multidimensional effective information learned from each network branch. We also compare and analyze five different classification techniques (i.e., k-nearest neighbor(KNN), decision tree(DT), support vector machine(SVM), random forest(RF), and XGBoost(XGB) $)$ and compare their performance statistically. After modeling the MGs system in the simulation software, the Consortium for Electrical Reliability Technology Solutions (CERTS) MG effectively illustrates the validity of our proposed method.","PeriodicalId":125983,"journal":{"name":"2022 IEEE International Conference on High Voltage Engineering and Applications (ICHVE)","volume":"23 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120909242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UHVDC converter station should take proper lightning protection measures to avoid lightning damage accidents. At present, to check whether the lighting arrangement scheme of the ±800kV UHV converter station is reasonable, the intruding wave overvoltage will be simulated. For Baihetan(Butuo) ± 800kV UHV converter station, some of the AC side incoming lines are installed with the shunt reactors and there is a long distance (more than 70m) between the shunt reactors and bushing (TG) of the AC side incoming section, while there was no lighting inrudign wave overvoltage research on such condition. In this paper, based on Baihetan ±800kV UHV converter station, the research on optimal layout of lightning arresters in AC side incoming section with shunt reactors were carried out by simulating intruding wave overvoltage using ATP-EMTP. Firstly, under preliminary arrester layout scheme the lightning intruding wave overvoltage were simulated. Secondly, under improved arrester layout scheme the lightning intruding wave overvoltage when the shunt reactor under operation were simulated. Thirdly, under improved arrester layout scheme the lightning intruding wave overvoltage when the shunt reactor out of operation were simulated. By study this paper gave the optimal layout of lightning arresters, and the research results have provided data support Baihetan ±800kV UHV converter station.","PeriodicalId":125983,"journal":{"name":"2022 IEEE International Conference on High Voltage Engineering and Applications (ICHVE)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120960418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a space charge measurement setup is proposed with tip-to-flat electrode configuration based on the pulsed electroacoustic method. The generation mechanism of the acoustic wave is firstly analyzed, based on which a simulation model is established to study the characteristics of acoustic wave generation and propagation. Compared with the conventional PEA, acoustic waves generating from bulk space charge and the surface charge at the interface of upper electrode and sample are not equal to the convolution of excitation pulse and space charge distribution. Negative overshoot appears in the acoustic wave due to the shape of upper electrode and uneven distribution of the electric field inside the sample. As a result, deconvolution and calibration methods in conventional PEA are not applicable anymore in this situation.","PeriodicalId":125983,"journal":{"name":"2022 IEEE International Conference on High Voltage Engineering and Applications (ICHVE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121426359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further enhance the output voltage amplitude, each Marx is stacked with short pulses from the transmission line transformer to achieve the high voltage amplitude output.
