In 2013, a group of researchers, including Dr. Gabriela Nicora, Prof. Marcos Rubinstein, Prof. Vernon Cooray, Prof. Francisco Román, and Prof. Farhad Rachidi declared themselves in favor of the development of an inexpensive sensor network, called AKUNU, which has for objective to collect atmospheric data in low- and middle-income countries. From the first prototypes, a data acquisition system was developed that records the electric field generated by a return stroke from a lightning using low-cost electronics. This was achieved between the University of Applied Sciences and Arts Western Switzerland (HEIG-VD) and the Institute of Scientific and Technical Research for Defense (CITEDEF of Argentina), where the Digital Techniques laboratory in conjunction with the Atmosphere laboratory continues and expands this research field with the development of a network of sensors to capture the electric field from atmospheric discharges, and of software applications for its analysis.","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":"82582314","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}

We will adopt two measures to reduce the capital investment costs of the lightning protection. Firstly, removing GW from new construction or renovation of distribution lines to reduce accidents caused by the fatigue disconnection of GW. Secondly, excluded the currently installed middle-phase arcing horns for the new distribution lines to reduce the maintenance cost of the lightning arresters within the arcing horn. However, the probability of a multi-phase flashover increased when the middle-phase arcing horn was excluded in all the medium phases in the twisted distribution line. In this study, we investigated the measures to improve the lightning protection performance of medium-voltage distribution lines that omitted middle phase arcing horn using the typical distribution configuration. We confirmed to greatly reduce the risk of lightning strikes by leaving the support bracket with the grounding line when removing the GW.","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":"84478606","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}

A partial element equivalent circuit model considering lossy ground is used for surge analysis, and the Monte Carlo method is adopted for evaluating the flashover rate. It is found that under extremely low soil conductivity, the simple vertical grounding rod is not effective in lightning protection, while the performance is significantly increased with extended counterpoise wires. The single-row counterpoise wire with a length of pole span performs best among the schemes of concern. The single-row counterpoise wire with a half-length of pole span is a competitive one, due to a half-cost reduction but a competitive performance with a difference of less than 9%. With the same total wire length, the scheme of single-row counterpoise wire is slightly better than the parallel-row arrangement. If a higher lightning protection level is required, the improvement could be achieved by increasing the CFO level or shortening the span of two adjacent surge arresters, since increasing the length of counterpoise wire is not cost-effective.","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":"84587878","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}

However, the total energy content of the comparable IEC impulse is higher than the real transient voltages. Thus, once tested and passed the endurance at laboratories such an energy absorbing device would not fail at the field applications against single real transient voltage. However the same cannot be guaranteed against the swarm of impulses as the same cannot be tested at the test bench due to many practical constraints. The study revealed that IEC impulses can accommodate only 2.31% of the total energy until it reaches to 90% of the peak voltage, whereas the selected real transient impulses have shown that they could accommodate nearly 6% to 18% of the total incident energy before they reach to 90 % of the peak voltage. Moreover, when IEC impulse reaches to the peak, it can incident only a 9.71% of the total energy, but real transient voltages demonstrated that they have a capacity to incident nearly 30% to 45 % total energy embedded in the impulse.","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":"83855586","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}
