Under actual operation conditions, GIS will withstand different kinds of voltages, such as DC, AC and impulse voltages. Under these conditions, there will be charges accumulated on the surface of GIS insulators, which can enhance the local electric field and even affect the flashover. In order to study the surface charge accumulation characteristics of actual GIS disc insulator in SF6 under different voltages, a disc insulator surface charge measurement system based on electrostatic capacitive probe is established in this paper. The surface charge measurement devices are controlled by the designed three-dimensional control mechanism, which can drive the probe to scan the insulator surface in both the circumferential and radial direction with high precision (1mm of radial direction and 1° of circumferential direction). The calibration experimental results shows the high precision and high sensitivity of this system. The charge resolution of the probe for the bevel surface could be up to 0.02106pC/(m2·nV) and the space resolution could be up to 6.3 mm2, the charge resolution of the probe for cambered surface could be up to 0.0303pC/(m2·nV) and the space resolution could be up to 4.4 mm2. The preliminary experimental results of surface charges accumulation on GIS insulator under AC voltage in SF6 which are obtained by designed system ensure the feasibility.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"47 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":"131339407","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}

XLPE is a widely used insulation material for HVDC cables. However, dealing with space charge accumulation in XLPE cables still remains a challenge. New insulating materials offer new possibilities facing these challenges, if their properties are well understood. Two model-cables with equal dimensions but different XLPE insulation are investigated in this study. One material is “conventional” XLPE, which is normally used for AC-cables, while the other is treated to introduce additional functionality into the polymer composition. The cables were exposed to a number of different combinations of applied electric field and isothermal temperature conditions, while space charge measurements on the samples were performed, using the PEA-method. The slight modification of the polymer composition of XLPE leads to considerable changes in space charge development. The modification influences injection, transport and recombination of charges in the sample.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"48 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":"122590883","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 state-of-the-art bi-axially oriented polypropylene dielectric film has a breakdown strength of >730 MV/m and low dielectric loss of <;0.0002 at 1kHz, but suffers a low dielectric constant of 2.2. Rational development of high permittivity polymers is undertaken with the guidance of a high throughput, first principles computation-based polymer design space search engine, parallelized with chemical synthesis and high field electrical characterizations. Further understanding of the correlation between materials' molecular and microscopic structures and electrical characteristics under high fields is essential to the rational design of new dielectric materials. In this paper, the electrical characteristics of a newly synthesized thiourea-etheramine copolymer with a dielectric constant of 5.5 were systematically investigated by a combination of broadband dielectric spectroscope, modified Sawyer-Tower polarization loop tester and pre-breakdown conduction measurements, to provide critical feedback for the rational design of polymers with high dielectric constant and low loss.","PeriodicalId":432404,"journal":{"name":"2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"37 8 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":"132892283","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}
