However, a conventional electric measurement method is difficult to detect the partial discharge signal, because the partial discharge includes the external noise produced by the electromagnetic wave. The purpose is the development of an optical magnetic field sensor system using Faraday effect that can detect the partial discharge. The characteristics of the system have no influence on the external noise. We developed the sensor for high frequency pulse current measurement. The sensor can respond to current in 13.56MHz. In pulse current, comparison of sensitivity is done in three kinds of sensor. Consequently, it was found that the sensitivity was influenced from distance between conducting wire and optical axis, therefore it didn't rise in 22kV-distribution system wire till to mA order.}, pages = {237--242}, title = {高周波パルス電流計測用光磁界センサの開発}, volume = {33}, year = {2004}, yomi = {イチマンダ, マサシ and サカタ, タカトシ and カトウ, エイジ and マツモト, シンゴ and ツジ, トシノリ and オオツボ, マサヒサ and ホンダ, チカヒサ and ババ, セイイチロウ and イクタ, マサテル and サカタ, タカトシ and マツモト, シンゴ and ババ, セイイチロウ} }
