However, traditional FDS testers are mainly designed for material measurement. Therefore, the test voltage used is usually not more than 2 kV, which led to unsatisfactory performance when measuring large power equipments. In order to obtain higher accuracy when measuring power equipments, taking into account that the increase in voltage makes it possible to find the connection between test voltage and dielectric spectroscopy, a high voltage dielectric spectroscopy measurement system for bushing moisture detection was designed. Firstly, the hardware architecture of the system was designed based on the FDS measurement principle. Then a prototype was built according to the design. The algorithm for data processing is also introduced in this paper. The measurement accuracy of the system was verified by comparison with a commercial FDS tester. Finally, two bushings with different moisture content was measured using the designed system. The results indicate that when the test voltage rises, the dielectric spectroscopy of the bushing with higher moisture content changes more significantly and regularly than the other. The feasibility of this system for bushing moisture detection is thus proved.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"12 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":"127901860","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 terahertz time domain system is used to test insulator models with different interface defects, and the characteristics of the time domain waveforms were analyzed. The test results proved the application value of terahertz wave in the detection of micro defects in the interface. The application scheme of the terahertz wave detection can be further explored.

Apart from traditional AC interconnection, High-Voltage direct current (HVDC) links provide an economic option to transport bulk energy. Especially on offshore platforms it is beneficial to use gas-insulated substations (GIS) due to the saline atmosphere and the limited space available. Considering technical and economic aspects, it is advantageous to use DC-GIS on those platforms. The constant electrical field in DC-GIS may lead to charge accumulation on gas-solid interfaces - e. g. on the interface between the low-conductive electrode coatings and SF6• Previous investigations revealed that this charge carrier accumulation can lead to surface discharges on coated electrodes which may reduce the dielectric strength of the whole insulation system. In order to understand these phenomena comparative experiments with low and high conductive electrode coatings were performed.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"1 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":"130717683","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}

Tir-post insulator is one of the most important component in GIL which supports the insulation and structure. However, defects of tri-post insulator will distort the electric field distribution, weakened the insulation, even cause the insulation failure. The safety will be threatened by the defects. So it necessary to analyze the effect law of the electrical field distribution by defects, and focus on the severe place which is in the most need to avoid defects in production process. In this paper, a part of GIL model was built by using COMSOL Multiphysics which included the tri-post insulator. Two kinds of linear defects which may easily occur on tri-post insulator were researched.

This paper presents a study of the negative lightning impulse breakdown voltages of pure water with and without nitrogen fine bubbles (N2-FBs). The breakdown voltages were investigated using sphere-to-sphere and plane-to-plane electrode configurations. As the result, it was found that N2-FBs tend not to be weak points of breakdown, but rather to raise the breakdown voltage. It was also found that the diameters of N2-FBs may vary depending on the produced location in an experimental container.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"38 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":"117134928","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}

Epoxy/hollow particle composites have been developed to produce composite materials with new functions such as a low dielectric constant, lightweight and high heat insulation. To understand the basic electrical properties of epoxy/hollow silica composites, breakdown voltage, capacitance, and partial discharge are measured. The breakdown strength of the epoxy/hollow silica composite and the breakdown strength of the epoxy/no hollow silica (normal silica) composite are almost the same regardless of the applied voltage waveform. The AC breakdown voltage at the 0-peak of the epoxy/hollow silica composite also agrees with the DC breakdown voltage. Furthermore, the sharing voltage of gas in hollow silica estimated by the partial discharge inception voltage and the electrical potential analysis exceed Paschen's voltage for the same distance. Breakdown is not determined by the continuous partial discharge in the hollow silica, suggesting that the interface between the silica particles and the epoxy resin may become the electrical weak point.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"44 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":"115552758","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, hydrocarbon-based thermosetting resins have not been put into practice as an electrically insulating material yet. Therefore, it is necessary to understand the electrical characteristics. Generally, when organic polymeric material is used as an insulator for high voltage equipment, a large amount of loading of inorganic fillers is needed so as to decrease linear expansion coefficient. Therefore, it is crucial to investigate the effect of inorganic filler loading on the various properties such as mechanical, thermal, and electrical properties for higher voltage and longer term operation of highvoltage equipment. From the viewpoints, this paper deals with electrical insulation properties of the hydrocarbon-based thermosetting resin with loaded micro silica particles. As a result, breakdown strength of hydrocarbon-based thermosetting resin is equal or higher than that of the epoxy resin. As a result, it can be said that the hydrocarbon-based thermosetting resin with lower viscosity and lower dielectric constant than the epoxy resin is promising as an insulating material for the next generation high voltage equipment.","PeriodicalId":377544,"journal":{"name":"2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP)","volume":"137 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":"116272512","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}
