By using a single-ended optical fiber around the current conductor that utilizes the magneto-optic effect (Faraday effect), FOCS measures uni- or bidirectional DC currents of up to 600 kA within +/- 0.1 % of the measured value.〔(【引用サイトリンク】url= http://www05.abb.com/global/scot/scot232.nsf/veritydisplay/74d5555d2a9c2998c12579a00038ff0a/$file/FOCS_brochure_3BHS362996_E01.pdf )〕〔(【引用サイトリンク】url= http://www.abb.com/product/seitp322/87658a38b941842dc1256f480034c11c.aspx?productLanguage=us&country=00 )〕 The benefits of the FOCS in comparison with conventional current sensors is that it doesn’t need recalibration after installation or at any point throughout its lifetime, and it’s unaffected by stray magnetic fields due to its optical measuring. Because of the latter there’s no need for magnetic centering, and there’s also no reduction in accuracy due to saturation effects.〔〔 The optical phase detection circuit, light source and digital signal processor are contained within the sensor electronics; this technology has been proven in highly demanding applications such as navigation systems in the air, on land and at sea.〔(【引用サイトリンク】url= http://www05.abb.com/global/scot/scot232.nsf/veritydisplay/74d5555d2a9c2998c12579a00038ff0a/$file/FOCS_brochure_3BHS362996_E01.pdf )〕 ==Applications== In 2013, ABB launched a 420 kV Disconnecting Circuit Breaker with integrated FOCS. Since one FOCS replaces many conventional current transformers, engineering and design of the substation is simplified. By reducing the material needed, including insulation, a 420 kV DCB with integrated FOCS can reduce a substation’s footprint by over 50% compared to the conventional solution of live tank breakers with disconnectors and current transformers.〔(【引用サイトリンク】url= http://search-ext.abb.com/library/Download.aspx?DocumentID=1HSM%209543%2021-10en&LanguageCode=en&DocumentPartId=&Action=Launch )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fiber optic current sensor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
