This source of lightning-fatality data is provided by the Colombian National Administrative Department of Statistics (DANE) and it has been preferred over other data collection methods because the information is obtained from a governmental free database that can be consulted by anyone with internet access. In addition, the relationship between the date, location of the event and some sociodemographic information of the victim, such as the gender and the occupation, are presented. Finally, the data set is also analyzed in order to establish a relation between the geographic distribution of the fatalities (location) and rainfall, where April-May and September-October are the two seasons with the highest rainfall, in which the most of the deaths by lightning has been reported for the 11-year period. These results can be used to increase the lightning safety knowledge and improve the management of the lightning risk in Colombia.","PeriodicalId":70714,"journal":{"name":"中国防雷","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90140761","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}

As the first step normality check was done for the data collected under the five variables which resulted in non-normal distribution in all five variables. Thereafter, the result of Mann-Whitney test proved that there is a significant distributional difference in PNBP and NNBP with respect to the five wave characteristics. Furthermore, they were used to fit a binary logistic regression model in order to model the odds of the occurrence of PNBP with respect to the significant variables identified in the Mann-Whitney test. This resulted RT, PD, SFD and ZCT to significantly explain the variability the response variable while FWHM did not significantly explained the same. In addition to that the overall fitted model was able to successfully explain 90.3% of the variability of the response variable. Finally, the change in odds were interpreted in terms of the significant predictor variables of the fitted model.","PeriodicalId":70714,"journal":{"name":"中国防雷","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88676400","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}

It frequently occurs, at a rate of 44 strikes every second, and it can cause severe damages to properties and endanger human lives either by death or permanent injuries. In Malaysia, lightning activities are one of the highest globally, and they have caused severe economic losses and human casualties. To avoid being struck by lightning, seeking shelter inside buildings is the standard action. However, there are doubts about how prepared buildings are to minimise the risk of human injuries and fatalities. In this project, lightning risk assessment and surveying of the existing Lightning Protection Level (LPL) of 22 buildings of different purposes in Cyberjaya, Malaysia were carried out. With the aid of the Malaysian lightning protection standards, MS IEC 62305, the risk of loss of human life (R1) due to direct strikes to buildings was calculated. In order to perform risk assessment, data were collected from different sources and using different methods including CAD drawings, physical inspections, direct measurements, interviews and inquiries from the management, and relevant online sources and publications. It was found that only less than half of the sampled buildings have adequate protection to minimise the risk of loss of human life. Finally, methods of risk mitigation for the unsafe structures were recommended to reduce the risk of loss of human lives to an acceptable level specified by the standards based on the significant factors contributing to the said risk.","PeriodicalId":70714,"journal":{"name":"中国防雷","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85257227","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}

Bentonite is very well known and word-wide acceptable clay which can be used to make the better interface between the soil and electrode, and hence total soil resistivity can be reduced. The resistivity of bentonite is highly moisture dependent which makes the clay insignificant in dry areas or the areas where resistivity of the soil is very high as per the literature and our experimental analysis. The issues associated with only clay could be solved with the addition of carbon particles in the clay, although that could not solve the issue of leachability completely. Therefore, an environment friendly chemical polymer entitled ‘link-X’ was added in the mix in order to maintain a reservoir in the soil along with the conductive components. The link-X can be used to make only carbon-based as well as bentonite-based earth enhancement compound. This could not only solve the problem associated with moisture but also could enable us to develop an environment friendly solution to retain the moisture for a long time.","PeriodicalId":70714,"journal":{"name":"中国防雷","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73568259","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}

Three widely used lightning attachment models in TL performance studies are implemented, namely: i) electrogeometric model (EGM) considering the constants suggest in the IEEE Std. 1243; ii) the attractive width approach proposed by Eriksson; and iii) the average attractive width, suggested by IEEE and CIGRE guidelines for estimating the lightning incidence to TL shielding wires and implemented in the IEEE FLASH program. Also, two different peak current distributions are analyzed, namely the classical Berger's distribution and another one representative of tropical regions. It is shown that using the concept of average attractive width leads to an overestimation of the lightning incidence to the shield wires of around 50%, taking as reference Berger's distribution. The EGM and attractive width approaches agrees fairly well in predicting the annual number of strokes to TLs. Furthermore, the annual number of strokes to TLs increases with the median peak value of the current distribution.","PeriodicalId":70714,"journal":{"name":"中国防雷","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74733835","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}
