Due to the high global warming potential and long atmospheric lifetime of SF6, there has been research into a new environmentally friendly replacement gas. This paper describes the research carried out at Cardiff University on CF3I gas and its mixture as a substitute insulation medium for SF6 in gas-insulated lines (GIL). A reduced-scale coaxial test system having the electric field properties of a full-scale 400 kV GIL system was fabricated. The design of the reduced-scale coaxial test system was simulated to ensure that the highest electric field would be along the center of the conductor. The coaxial prototype was then tested under a standard lightning impulse (1.2/50) in order to determine the 50% breakdown voltage for such a system when insulated with CF3I gas mixture. It was found that CF3I has the potential to replace SF6 as an insulation medium in GIL. A full-scale short length GIL demonstrator is being assembled in the laboratory to evaluate further the feasibility of using a CF3I gas mixture as an insulation medium.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115237913","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}

Compared to other procedure in generating atmospheric pressure plasma jet, the application of the dielectric barrier discharge (DBD) is comparatively simple. However, the details regarding the electric discharge properties and active species' forming reaction is still unclear. It is also important to understand the plasma generation region, which is the key component of DBD for the application in future works. Therefore in this work, the generation region of Ar plasma caused by dielectric barrier discharge was investigated. The atmospheric pressure plasma generating device used in this experiment was constructed by covering a part of a copper pipe, which act as an electric discharge electrode with a silica glass pipe. As a grounding electrode, the exterior part of the silica glass pipe was wrapped with a copper foil. This plasma was examined using emission spectroscopy method from the side of the silica glass pipe. The copper foil was provided with a slit for measuring the emission spectroscopy in the grounding electrode area. The measurement was ranged from the edge of copper pipe until the end of plasma emission. From the results, spatial emission spectrum of excited Ar had shown different emission intensity according to the point location. This paper discusses about the spatial emission characteristics by focusing on the dielectric barrier.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124394811","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}

However, because of their dielectric properties, these materials can accumulate charges in the insulation, generated by dissociation of species or injected at the electrodes. This accumulation phenomenon can cause an increase of the electric field which can lead to the dielectric breakdown of the material, meaning thereby stopping the distribution of electricity. It is therefore important to understand these charge accumulation mechanisms for HVDC application, and particularly the role of ions, generated by dissociation of by-products of cross-linking agents, that can transport and take part to space charge accumulation. In this goal, we have considered a simple model material consisting of low-density polyethylene (LDPE) films soaked in cumylalcohol, a by-product often encountered in peroxide-crosslinked XLPE and thought to dissociate under field to provide ionic carriers. The impact of the soaking time, electric field and temperature on space charge density profiles recorded using the Pulsed Electro Acoustic method (PEA) and on charging current are presented and compared to those obtained on un-soaked LDPE samples.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127324264","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}

DBDs inside the cavities lead to phenomenological hysteresis curves that can in principle not be distinguished from those on other ferroic materials. Here, the influence of the gas temperature on the hysteresis loops of ferroelectrets has been studied over a wide temperature range from -100 to +140°C. In order to minimize temperature-induced changes in the geometry of the cavities and in the charge-storage behaviour of the dielectric, mica sheets were employed for assembling the ferroelectret systems. The coercive voltage and the effective polarization of the mica ferroelectret samples were determined as functions of the temperature of the sample and its gas-filled cavities. The results are discussed with respect to Paschen's law for electric breakdown - taking into account the respective gas temperature. It is shown that the threshold voltage decreases with increasing temperature. Therefore, the charging or poling temperature is an important parameter that strongly affects the phenomenological coercive field and the remanent polarization of ferroelectrets. The results should be taken into account when optimizing the charging process of ferroelectrets.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124935273","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}
