ELECTROMAGNETIC NOISE MEASUREMENT SYSTEM

PROBLEM TO BE SOLVED: To enable a simple configuration to independently measure electromagnetic noise in each vehicle without being subject to a limitation of a measurement condition or a position in an electromagnetic noise measurement system intended for a railroad vehicle.SOLUTION: An electromagnetic noise measurement system is intended for a railroad vehicle measuring electromagnetic noise generated in the railroad vehicle, and has: an electromagnetic noise detection line that is also arranged in any of an electric wire bundle drawn-in fixed to at least one of an interior of a vehicle of a railroad vehicle formation or an exterior thereof; and an electromagnetic noise evaluation device that includes a voltage acquisition unit that acquires potential between two points. One end of the electromagnetic noise detection line is connected to a metal portion of a vehicle body via resistance, and the other end thereof is connected to the electromagnetic noise evaluation device. The voltage acquisition unit is configured to acquire potential between the other end of the noise detection line and the vehicle body.SELECTED DRAWING: Figure 1 【課題】鉄道車両向けの電磁ノイズ計測システムにおいて、簡易な構成で、測定条件や位置の制限を受けず、各車両で独立して電磁ノイズを測定可能なようにする。【解決手段】鉄道車両に発生する電磁ノイズを計測する鉄道車両向けの電磁ノイズ計測システムであって、鉄道車両編成の車両内または車両外の少なくとも一方に引き通し固定された電線束の何れかに併せて配置される電磁ノイズ検出線と、２点間の電位差を取得する電圧取得部を含む電磁ノイズ評価装置とを有する。そして、電磁ノイズ検出線の一端は抵抗を介して車体の金属部分と接続し、他の一端を電磁ノイズ評価装置と接続し、電圧取得部はノイズ検出線の他の一端と車体間の電位差を取得する。【選択図】 図１
