NUMERICAL CALCULATION OF PLANE GROUND INFLUENCE ON INDUCED CURRENT ON CABLE BY EMP

  • 摘要: 與電子系統(tǒng)相連的電纜被電磁脈沖感應(yīng)形成的脈沖電流,構(gòu)成了對電子系統(tǒng)的嚴(yán)重威脅。該文用時域有限差分法計算了大地電參數(shù)對感應(yīng)電流的影響。計算獲得了電纜上皮電流與電纜距地高度的關(guān)系,并與自由空間的結(jié)果進(jìn)行了比較。
    Abstract: The induced pulse current by EMP on cable that is connected to electric system threatens seriously the system. In this paper, the influence of conductivity and permittivity of plane ground on this current is calculated by FDTD method. The relationship between induced current and cable position above the earth is obtained, and the results are compared with the free-space case.
