It is a very important matter by what kind of informations the line currents should be represented. The authors adopted the method of dividing the current vector into the absolute value and the phase. Both informations are sampled and quantized during the same time as the half period of the line current, and then the transmission and the comparative operation of the informations at both terminals of the line are accomplished during the same time following. Using the unit integrator, the analogue to digital converter for the absolute value of the current, developed for this system and the phase comparative system by logical operation ; the protective relay system is obtained, which puts out the command signal of trip, in spite of the comparatively simple construction, within 1. 5 cycle of line frequency after the fault happens in the power line.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 30: 53-66 (1971)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"永野,  泰男","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柳沢,  俊彦","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering30-04.pdf","filesize":[{"value":"717.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering30-04.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13006/files/Engineering30-04.pdf"},"version_id":"8598a8b9-c3ff-404b-810f-5f98bed6109c"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"PCM 伝送による電流比較継電方式","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PCM 伝送による電流比較継電方式","subitem_title_language":"ja"},{"subitem_title":"Protective Relay System Using PCM Transmission Method","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1277"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"13006","relation_version_is_last":true,"title":["PCM 伝送による電流比較継電方式"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:43:24.457621+00:00"}
