Claims (1)
- E線、N線、接地線からなる単相三線式商用交流の給電部に接続されて電力供給を受け、電源ラインを所要の特性インピーダンスに安定化して商用交流電源から電磁雑音を除去し、E線もしくはN線の何れか一方と各々接続される第1給電ラインおよび第2給電ラインから電磁雑音の除去された電源を供給する電源インピーダンス安定化手段と、
前記電源インピーダンス安定化手段の第1給電ラインおよび第2給電ラインを介して供給される電磁雑音の除去された電源を供試装置へ供給する給電部と、
前記電源インピーダンス安定化手段と前記給電部との間に設けられ、外部導体で囲んだ筐体の内部に、第1給電ラインに接続される第1内部導体と第2給電ラインに接続される第2内部導体を有する電磁遮蔽体と、
前記電磁遮蔽体の内部において、第1内部導体に生ずる電磁界と第2内部導体に生ずる電磁界が均等に作用するように配置した電磁界検出手段と、
を備え、
前記給電部より供試装置へ電源供給したとき、第1給電ラインを流れるディファレンシャルモード電流で第1内部導体に発生する電磁界と第2給電ラインを流れるディファレンシャルモード電流によって第2内部導体に発生する電磁界が相補的に打ち消し合うことで電磁界検出手段には作用せず、第1内部導体と第2内部導体を流れるコモンモード電流によって発生する電磁界のみを電磁界検出手段によって検出させ、コモンモード伝導妨害波を測定することを特徴とするコモンモード伝導妨害波測定装置。
