In this paper, the experimental circuit was setup and the DC breakdown characteristics of MOV with series gap were researched. The influence laws between the breakdown current and DC breakdown voltage of MOV with series gap were obtained and the experimental results showed that the DC breakdown voltage of MOV with series gap increases with the increase of breakdown current when breakdown current is less than 1mA. When the breakdown current is controlled between 1mA and 5mA, the DC breakdown voltage of MOV with series gap is equal approximately to the sum of the DC reference voltage of varistorU1mA and the breakdown voltage of series gap. And the turn on voltage is depended on the limited voltage of varistor and the arc voltage of the series gap, the uncertainty of the measuring instrument is less than 1% comparing with verified Tektronix oscilloscope TDS2012. Then the simulation circuit model of the MOV with series gap is established, the voltage and current characteristics are studied when DC high voltage is applied, and the experimental results are explained effectively.","PeriodicalId":393969,"journal":{"name":"2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130338523","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}

In the past, the minimum air gap distance is decided by the test result under standard switching pulse voltage. The using of long front-time pulse voltage generator can get the air-gaps discharge characteristic, which is more similar in UHVAC system. In this case, the design of UHV substation is not only safe, but also economical. In this paper, the air gap between several typical electrodes and ground in UHVAC substation, including the conductors to ground, the grading ring to ground, is tested under the voltage, whose waveform is standard switching pulse voltage, 1000μs long front-time switching pulse voltage and 2500μs very long front-time switching impulse voltage. The key curve of the air-gaps discharge characteristic is received. The different of discharge voltage under several front-time switching impulse voltages is studied, and the effect of switching pulse voltage's front-time on the discharge voltage of air gap is received. The result shows that the discharge voltage is increasing by the fronttime extending, but growth rate is decreasing by the air gap distance lengthening.","PeriodicalId":393969,"journal":{"name":"2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117061075","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}

Polarity reversal is a special working condition of converter transformer in service, and the polarity reversal test is also generally regarded as the most important experiment for converter transformer. In the calculation of the polarity reversal field, the permittivity and conductivity of the each dielectric material should be given. The insulation materials of converter transformer are oil and pressboard. The resistivity of pressboard is anisotropic, there is a great difference value between the directions of through and along the paper layer. Different polarity reversal durations have different experiment results during polarity reversal test process. In this paper, the electric field distribution of converter transformer valve side winding in a practical ±800 converter transformer under polarity reversal test voltage was calculated with field-circuit coupling method. The anisotropism of paperboard resistivity was taken into account during the calculation process. In order to analyse the influence of polarity reversal duration to the distribution of electric field, several different polarity reversal durations were set to contrast. The results of this paper could provide references for the research and design of converter transformer.","PeriodicalId":393969,"journal":{"name":"2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124796061","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 electrical parameters including applied voltage, total discharge current and transported charges are measured and calculated, respectively. Results show that the total discharge current has two obvious spikes. The first current spike of the total current has a peak which results in some fluctuations of transported charges in V-Q Lissajous figures, but the peak of the first current spike hardly changes with the electrode's width. The second spike peak value increases with the electrode's width, and reaches its maximum at an optimum width. All the V-Q loops at different electrode's widths are “almond-shape”, and the transported charges and energy per pulse increase with the electrode's width. The main plasma action area increases with the electrode's width, but keeps relatively constant when the grounded electrode's width is larger than the optimum width. In addition, the grounded electrode's width has no obvious influence on the plasma light intensity.","PeriodicalId":393969,"journal":{"name":"2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121868044","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}
