They are horizontal wires buried in the earth at a depth of about a half meter, and tied to the tower base. Regarding the counterpoise as an electric circuit of one conductor with distributed line constants, we analyze the input impedance of the counterpoise for an applied impulse voltage by the basic theory of distributed constant circuit. The variation of the input impedance with time is as follows: It starts with the initial surge impedance, and subsides exponentially to the final leakage resistance of the counterpoise. The impedance characteristics of the counterpoise may be classified into (1) the inductive, (2) the capacitive, and (3) the resistive types depending on the effects of the resistivity of the soil, the length of the counterpoises and the number of the parallel counterpoise wires. The results of the analysis are confirmed by comparison with those of a series of field tests carried out by Research Laboratory of Shikoku Electric Company. It will be worthy of notice that the assembly of several short counterpoise wires acts as the capacitive circuit under special conditions.","subitem_description_type":"Other"}]},"item_1_full_name_7":{"attribute_name":"著者名よみ","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41252","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ナカザワ, ツトム"}]}]},"item_1_full_name_8":{"attribute_name":"著者名(英)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41253","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakazawa, Tsutomu","nameLang":"en"}]}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00217655","subitem_source_identifier_type":"NCID"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"論文"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"福山大学工学部電子電気工学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1979-01-01"}],"displaytype":"detail","filename":"KJ00005780903.pdf","filesize":[{"value":"500.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://fukuyama-u.repo.nii.ac.jp/record/7593/files/KJ00005780903.pdf"},"version_id":"25f17bc4-e322-4f19-baf7-ec8e7d32db80"}]},"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":"衝撃電庄による埋設地線のインピーダンス特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"衝撃電庄による埋設地線のインピーダンス特性"},{"subitem_title":"Input Impedance Characteristics of Counterpoises for an Impulse Voltage Wave","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["676"],"pubdate":{"attribute_name":"公開日","attribute_value":"1979-01-01"},"publish_date":"1979-01-01","publish_status":"0","recid":"7593","relation_version_is_last":true,"title":["衝撃電庄による埋設地線のインピーダンス特性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T10:40:17.245918+00:00"}
