This paper presents the holding effect on the noise performance of the model transformer cores. The results shows that the noise of lifted model core is 1.5dB lower than that of self-standing model core. Analysis of the noise frequency components indicates that the dominant frequency component is 300Hz, and that the noise of lifted core is lower than the self-standing core noise.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e347Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 1","offer_id":49643086840047,"sku":"IEEJ-BTA2025-3-C-a2-5-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_81744480-8696-4142-bf5d-96c86a5e5fb5.png?v=1780541732","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-bta2025-3-c-a2-5","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
