Dielectric properties of the nanoclay coatings along with their nanostructure characterization were studied for the coating processing optimization. The DC breakdown strength test and small-angle x-ray diffraction results consistently indicated that dip coated samples led to the most highly oriented nano-Iaminated structure with the highest breakdown strength. Corona endurance test was also performed on dip coated MMT nano-composite materials in comparison with other commercial available discharge resistant film. A remarkable enhancement was observed for nano-Iaminate coating, which indicated that this new nano-composite material has potential to be a processable and cost-effective dielectric material for many applications where discharge resistance device/structure/materials are needed.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132808724","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 measurements investigate the cable compounds over a broad frequency range (between 1 Hz and approximately 100 MHz) at a defined temperature (20°C), humidity and pressure. The measurement results give the complex permittivity and the resistance or conductance of the semiconductive samples. The samples are extracted from regular energy cables and characterized in preparation for measurement. Due to the sample preparation and extraction from the cable, the samples are slightly different in their geometries, and therefore the geometrical data for each measured sample are taken into account in the calculation, and hence in the measurement results. The investigated samples are extracted from a 380 kV, a 110 kV and a 15 kV energy cable. The samples are different in their semiconductive material compounds; a better compound is used in the 380 kV cable than in the other two. The compound was from Borealis for all sample types. The compound LE 0500 is used for the 380 kV cable and LE 0595 for the 110 kV and 15 kV cable samples. The investigation results are separated by voltage level and position in the cable. The position refers to either the inner or the outer semiconductive layer. The paper is separated into a brief overview of the measurement setup, basic details of the semiconductive layers/compounds, the extraction of the samples and the measurement results. The results show the difference in the compounds and the variation in the samples.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133103744","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}

When the DC voltage applied to the MI PPLP cable is above partial discharge inception voltage (PDIV), partial discharge occurs in the void. The continued partial discharge accelerates electrical ageing and breakdown may occur as a result. Hence, it is necessary to study the correlation between partial discharge inception and breakdown in DC steady state. Partial discharge and breakdown in the DC steady state are affected by the temperature and the polarity of the applied voltage. Therefore, in this paper, to analyze the correlation between PDIV and Breakdown Voltage (BDV) of butt-gap in HVDC MI PPLP cable, BDV and PDIV measurement were performed according to temperatures of the specimen and polarities of the applied voltage. From the experimental results, The BDV of the butt-gap in the MI PPLP was found to be inversely proportional to the conductivity and proportional to PDIV. Also, PDIV and BDV were higher at negative voltage compared to positive polarity voltage. Consequently, BDV can be predicted through the temperature of the MI-PPLP and PDIV.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128795859","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 aging process of silicone oil is considered as the main reason of the accidents occurred on the oil-filled terminals. It is observed that gas generation occurs in the aging process of silicone oil. This paper focuses on the relationship between the gaseous product generated by spark discharge and the aging status of the silicone oil. In the present study, a needle-plate electrode is used to simulate the aging process of the silicone oil, and a gas chromatograph is used to analyze the gases generated during the discharge. Dielectric loss tangent and volume resistivity are measured to characterize the aging state of the silicone oil. The volumes of each kind of gaseous product increase with cumulative discharge quantity, and carbon monoxide and hydrogen occupy the largest proportion. When the experimental silicone oil reaches the aging status, acetylene appears and the volume of hydrogen increases rapidly, so the appearance of acetylene and the proportion of hydrogen reaching 6% in total gaseous product are the symbol of the aging of silicone oil.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127832795","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 addition, the degradation of low-density polyethylene (LDPE) under thermal aging can increase the space charge accumulation, but the nanoparticles can enhance the ability of LDPE to suppress space charge. However, the ability of nanocomposites to suppress space charge under thermal aging needs to be further studied. In this paper, the space charge accumulation characteristics and the crystallinity of pure LDPE and LDPE/TiO2 samples under thermal aging were carried out with a pulse electro-acoustic method (PEA) system and a differential scanning calorimeter (DSC). It is concluded that the TiO2nanoparticles can improve the crystallinity of LDPE, and the ability of LDPE/TiO2 to suppress space charge is significant with the TiO2mass concentration of 1wt%. In addition, thermal aging can damage the microstructure and reduce the crystallinity of materials, increasing the sources of space charge. Combining the theories of interfaces, charge traps and electrode injection barrier, it can be concluded that the TiO2nanoparticles can decrease the sources of space charge, and the ability of LDPE/TiO2 to suppress space charge is mainly related to the increase of crystallinity. In general, thermal aging has an important influence on the space charge characteristics in LDPE, and TiO2nanoparticles can suppress space charge and delay the process of thermal aging. Therefore, LDPE/TiO2 nanocomposites still can suppress space charge under thermal aging.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123040921","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}
