In the area of developing innovative methods for theoretical and experimental study of the electromagnetic and thermal behavior of new types of ReBCO-, BSCCO-, and MgB2-based high-temperature superconductor (HTS) tape and windings with innovative configurations for prototype devices for the power grid, research activity is currently being directed mainly in two directions: developing theoretical and experimental analyses regarding possible innovative winding modes for HTS tapes for applications in the power grid; developing numerical models for the behavior of coils made with layered windings (as opposed to pancake coils made) in non-insulated or metal-insulated mode.<\/p>\n
<\/p>\n
In this report, which is part of the main body of RSE’s experience in the design, development, characterization, and testing of SAT windings for superconducting fault current limiters (SFCLs), a number of relevant issues are addressed when designing devices that require superconducting windings. In particular, results are reported on the development of simplified equivalent circuits for the representation of non-insulated helical multilayer windings; on the modeling of first-generation HTS coils both with and without electrical isolation between turns.<\/p>\n
<\/p>\n
The test set-up used for the measurement of AC losses produced in windings is then described; and a theoretical and numerical analysis for the processing the results of AC test on straight HTS samples; tests for the determination of AC losses in straight HTS tapes at various temperatures (65 K \u2013 77 K); and studies for the realization of innovative sample holders for the study of multiple test configurations.<\/p>\n
<\/p>\n
The report suggests continuing the activities by validating the proposed equivalent circuit (and\/or possibly developing new interpretative models) by comparison with the experimental results obtained on multilayer helical coils made with the innovative \u2018L-shaped\u2019 clamp holder described in this report. In addition, the experimental AC testing campaign on new supplies of HTS tapes will be continued.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":185749,"id":185749,"title":"22014001","filename":"22014001.pdf","filesize":25012344,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2024\/02\/22014001.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/approfondimenti-e-integrazioni-sulle-attivita-di-modellazione-e-caratterizzazione-sperimentale-di-nastri-e-avvolgimenti-sat\/attachment\/22014001\/","alt":"","author":"93","description":"","caption":"","name":"22014001","status":"inherit","uploaded_to":185746,"date":"2024-02-08 09:35:33","modified":"2024-02-08 09:35:33","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2022-12-31","autori":"M.
