As the vegetable insulating oil is increasingly used in transformers while its physical and chemical properties are different from those of mineral oil, special attention should be paid to the influence of particles on its dielectric strength. This paper investigated the influence of nonmetallic particles, namely carbon particles and cellulose particles on the breakdown strength of vegetable insulating oil. The breakdown voltages of vegetable insulating oil and mineral insulating oil contaminated with carbon particles or cellulose particles of different sizes and particle numbers were measured, respectively. The relationships between the breakdown voltages and particle numbers were obtained. The experiment results showed that the breakdown strengths of the vegetable insulating oil decrease with the increase of the particle number, and the breakdown voltages and the denary logarithm of particle numbers approximately satisfy the linear correlation, which is the same for mineral insulating oil. More importantly, the vegetable insulating oil is less sensitive to the particles compared to mineral insulating oil in terms of breakdown voltage, which might be due to its higher viscosity. Therefore, different standard of particle limit should be established for vegetable insulating oil.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"1 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":"125883062","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}

Most chemo drugs aim any one of these receptors to treat TNBC. Since all the three receptors are lacking, it is very difficult to treat this disease. In addition, due to the nature of these cells, they also are partially insensitive to many chemo drugs. It is of practical interest to treat them with alternative and physical therapies, possibly with no drugs, knowing the extent of damages/side effects caused by the chemo drugs and one potential candidate is irreversible electroporation-use of electrical pulses to ablate the tissue with no drugs. Since no drugs are used and only electrical pulses are involved, it is an attractive alternative for especially those cases, where current standard of cure for cancer, including surgery, chemo, radio, and hormone therapies do not work. In this research, we studied the efficacy of electrical pulses in reducing the proliferation of MDA-MB-231, human, triple negative breast cancer cells using various numbers of pulse intensities and found them to be effective.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"16 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":"125572243","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}

Individual vented tree configurations are modeled under Comsol Multiphysics environment. To understand the mechanism of involved phenomena, an evaluation of the electric field distribution is carried out. The influence parameters adopted in this investigation are: the permittivity, the length of the water trees and the magnitude of the space charges. The results of investigation showed that, in the absence of space charges, water trees lead to a local increase (respectively decrease) of the electric field in the outside (respectively inside) areas of these trees. However, the accumulation of space charges induces a significant variation of electric field inside and outside the trees and in the volume of insulation. In fact, the electric field repartition depends on the magnitude of space charge density and space charge layer dimension. According to this repartition, the dynamic movement of the space charges is evoked.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"19 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":"125250802","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}
