Critical flashover overvoltages (CFOs) and volt-time curves of 15-kV and 25-kV class, pin-type porcelain insulators are determined from experimental tests with both standard and non-standard voltage waveforms. The tests are performed for configurations that are representative of medium-voltage distribution lines. Parameters are derived for application in the integration method, which is intended to model insulator performance due to non-standard voltage waveforms. The obtained parameters are used in computer simulations that show the influence of insulation breakdown on lightning-induced voltages considering different flashover criteria. The obtained results suggest the importance of an accurate flashover modeling for a correct assessment of lightning overvoltages in distribution systems.","PeriodicalId":277573,"journal":{"name":"2011 International Symposium on Lightning Protection","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115658230","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 evaluated surge arrester models presented similar results for 8/20 µs discharges, once that they were fitted for this kind of transient. However, for 1/2 µs discharges substantial differences were obtained, mainly, between the dynamic models and the conventional model. For this kind of discharge the dynamic models have shown plausible results.","PeriodicalId":277573,"journal":{"name":"2011 International Symposium on Lightning Protection","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129181113","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}

Whereas the electric and electronic equipment can be protected by a comprehensive surge protection concept, outer structures particularly the rotor blades are hit by direct lightning strikes. In defined maintenance cycles these damages are inspected and repaired in costly operations. In this paper a method for lightning current measurement is presented. It enables the operator to measure lightning currents directly and to determine their parameters like amplitude, current rise time and charge. The presented system with three sensor units is originally developed for wind turbines, to adapt maintenance cycle times to the real number of lightning strikes. Further applications in other industries are possible.","PeriodicalId":277573,"journal":{"name":"2011 International Symposium on Lightning Protection","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128770362","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}
