After the reprocessing, the ENTLN performance characteristics changed (relative to those corresponding to the originally reported data) as follows. Flash detection efficiency increased from 80% to 89%, stroke detection efficiency increased from 49% to 67% percentage of misclassified events decreased from 60% to 52% median location error increased from 621 m to 687 m, and median absolute current estimation error decreased from 51% to 17%.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"50 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":"121792483","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 innovation is the use of a very short current reaction lead, which is possible due to the use of transmission line with very low propagation velocity (3% of the velocity of light). The methodology for obtaining the transient impedance from the measurements is discussed and validated. The experimental results regarding transient impedance measurements for two ground electrodes arrangements are presented. The first arrangement consists of two vertical rods and the second one is an actual 138 kV transmission line tower leg, composed by a vertical electrode in parallel with a horizontal wire. A comparison with calculated values for both cases is also presented.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"16 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":"129756455","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 lightning data used to monitor lightning activity in this study was recorded by the sensors of the BrasilDAT lightning location system. The dataset consists of cloud and cloud-to-ground discharges detected within a 100km-radius circle centered on latitude -23.4587° and longitude -46.7667°, corresponding to an area in and around the city of São Paulo, SP, Brazil.

In this case, the arrester's automatic disconnector should actuate, disengaging it from the network and indicating the necessity of the arrester replacement. The problem is that these disconnectors present a random actuation, sometimes bursting in normal operation conditions, others, not actuating when necessary. This behavior may be extremely detrimental to the network, as it may indicate the removal of good arresters or, on the other hand, allow the immovability of defective ones. This paper presents an study on the behavior of automatic disconnectors, in field and laboratory, and suggestions for the improvement of these components.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"82 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":"128044066","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}
