Results show that as Tf increases, the 50% breakdown voltages decrease to a minimum value and then increase. When Tf exceeds 2.0 μs, the 50% breakdown voltage is higher than that of standard LI obviously. The standard or impulse LI test with Tf ? 1.56 μs is to be preferred for installation detection, for it offers a greater probability of detecting insulation defects.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e英語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ: \u003c\/strong\u003e421 K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":46401393197295,"sku":"IEEJ-ZT177078-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_c8c133a0-6597-4c38-9edf-e0807d5191e0.png?v=1744942005","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-zt177078","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
