The tortuosity of the channel is reproduced by means of a numerical algorithm that takes into account statistical characterizations made by different authors observing real lightning channels, so the macroscale tortuosity of the simulated channel is similar to the one recorded in nature. Later it is used an analytic model which allows the calculation of the electromagnetic fields generated by lightning channels with tortuous geometries, once the geometry is known. The electromagnetic fields are calculated assuming a Heaviside step function as the current traveling along the channel. The objective of this work is to analyze two factors that could cause error in the time-of-arrival technique for lightning localization: the change in the electromagnetic wave shape around the channel and changes in the magnitudes of the measured fields for the same distance from the base of the channel but different azimuth angle.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"12 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":"114987019","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 study analyzed the lightning parameters based on the new antennas network called LINET. The lightning parameters under study are: return stroke current, polarity and ground flash density. These preliminary results will be the support of future investigations about the lightning parameters characterization and also could help to adjust the characteristic equations and typical values of the phenomena for lightning protection systems in the Caribbean region.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"444 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127606062","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}
