The proposed method uses the Electrogeometric Model to define the strike range limit, such that the generated events fall inside the range that would cause insulation failure. In this way, the non-potential strike events are excluded before carrying out additional computations, without requiring any complex algorithm for the event filtration. This method has been implemented to assess 17 arrester-based protection schemes with different arrester spacings. The assessment revealed the overvoltage impact levels at different nodes of the network concerned in the case study. It is proposed that the commonly accepted fact that the impact level generally increases with the increasing arrester spacing, may not be always true. Instead, there can be a range of spacing distances with abnormalities. Also, it was noted that the severity ranking of the distribution transformers in the assessed network varied with the protection scheme. Thus, it is recommended to perform a prior analysis in implementing a planned protection scheme.","PeriodicalId":403323,"journal":{"name":"2022 36th International Conference on Lightning Protection (ICLP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129815149","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}

This survey had as main objective to be applied to a lay public and with little technical knowledge about lightning in order to verify the general knowledge of the population and its main beliefs and myths. The questionnaire was released to be answered through the Google Form tool. The total number of responses obtained was 928, the vast majority by people from the state of São Paulo (~70%) and with a high level of education (~80% with higher or postgraduate degrees). This sampling was not very good because we would like to have a more comprehensive sampling in terms of the various Brazilian states and also regarding the education that did not reflect the Brazilian population in general. Thus, the research result was impaired, reflecting only a small part of the Brazilian population. Despite this, for the public that the research reached, even with high education, the result of the research suggests the need for a great effort of communication about the dangers that involve the occurrence of lightning and the good practices of behavior in front of them. At this point, there is a divergence from the Malaysian survey, which has a more uniform instruction and the same level of responses.","PeriodicalId":403323,"journal":{"name":"2022 36th International Conference on Lightning Protection (ICLP)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114572830","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}

Pretorius","doi":"10.1109/ICLP56858.2022.9942554","DOIUrl":"https://doi.org/10.1109/ICLP56858.2022.9942554","url":null,"abstract":"The international standard IEC 61400–24, addressing specifically lightning protection of wind energy systems, was introduced in 2010 with a revision and update of the standard published in 2019. This international standard presents guidance, through high voltage and high current tests, on the specific evaluation of wind turbine blades against lightning damage. Despite this guidance, a significant number of blade-damage-cases are still being reported, making it an important consideration in view of the growing number of wind farms employed in renewable energy projects worldwide. This paper indicates that lightning ground potential rise, including travelling waves and reflections from the foundation of the wind turbine and other bonded parts of the wind turbine, can set up potentials inside the blade that are large enough in magnitude to cause the breakdown of the composite material which the blade is manufactured from. Potentials set up in this manner are not tested for under the existing test regime covered by IEC 61400–24. The paper further shows the importance of earthing / bonding and protection of specific components, such as sensors, heating systems and carbon strips applied in the blade. When not done correctly, the implication includes mis-assignment of the lightning protection zone inside the blade, as recommended by secondary standards / specifications, and an underestimation of the lightning risk associated with the wind turbine blades. Based on the findings of this paper, it is strongly recommended that the testing techniques covered in IEC 61400–24 should be updated to incorporate the anticipated damage mechanism presented by ground potential rise (and associated travelling waves and reflections). This will require some form of model of the entire tower plus the foundation and accompanying soil conditions.","PeriodicalId":403323,"journal":{"name":"2022 36th International Conference on Lightning Protection (ICLP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124760199","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}
