A dc-voltage, which increased linearly in time, was applied to a test cell with tip-plane electrode geometry. By careful mechanical design of the test cell a defined wave impedance of the whole experimental set-up was realized. A capacitive voltage divider was integrated into the high voltage feed to the tip electrode and the plane electrode was connected to ground via a coaxial measuring resistor. Data were taken for 1 mm and 2 mm electrode separation and for both polarities of the tip electrode. The temporal variation of the spark resistance R(t) was calculated and a general equation for R(t) was derived.","PeriodicalId":181633,"journal":{"name":"1984 Eighth International Conference on Conduction and Breakdown in Dielectric Liquids","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116738140","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 fundamental role of the double layer is emphasized, especially how the compact part and/or the diffuse part of this layer control the current flow according to the amplitude of the field. Several electrical and optical techniques were used to study propylene carbonate up to 500 kV/cm. The unique curve describing the current-field variation is in good agreement with the Félici's model based on electrochemical kinetics, the field at the injector being corrected because of space charge and electrohydrodynamic flow.","PeriodicalId":181633,"journal":{"name":"1984 Eighth International Conference on Conduction and Breakdown in Dielectric Liquids","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128641675","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 experiments have been carried out, at room temperature, on two 50 cSt viscosity polydimethylsiloxane silicone oils (Rhône-Poulenc 604 V 50 and Dow Corning 561) in a parallel plate conductivity cell as a function of the applied electric field strength (0.4 ≦ E(kV.cm−1) ≦ 10), of the cell gap (0.05 ≦ d(cm) ≦ 0.55), of the oil viscosity (50 cSt to 300 cSt) and of the oil purity. From our measurements we can assert that: 1) the peaks appearing on the wave forms corresponding to the commercial oils are due to some impurities present in these oils; 2) these peaks cannot reflect the migration of a charged layer between the electrodes; 3) they are more certainly correlated to some dipole reorganization near the electrodes after each voltage polarity reversal.","PeriodicalId":181633,"journal":{"name":"1984 Eighth International Conference on Conduction and Breakdown in Dielectric Liquids","volume":"74 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131178092","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}
