The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

要約

The breaking devices improvement is an important research area. High temperature phenomena, creating ablation on both contact materials and walls of the breaking chamber are very complex to understand, and so to model, because of the electric break arc phenomena complexity, but also because of the breaking device complexity.
As many parameters are involved in arc behavior understanding, the most reliable solution to determine the influence of one parameter is to realize parametrical studies, based on measurement.
Breaking devices manufacturers try to carry on such studies, but they are limited by available means of diagnostic. The aim of our study is to offer a precise, reliable and powerful diagnostic tool, using magnetic measurement, enabling to know the arc shape and position with a cadence of 1 million frames per second.
This tool has been used to determine the geometrical dimensions influence on the breaking device quality. The geometrical configuration influence on the thermal erosion of breaking device elements has specially been investigated. Results obtained especially show the advantages of a breaking chamber associated with a very confined volume for performance improvement of breaking devices.
