但由于超高压输电线路导线的表面电场强度均控制在电晕临界电场强度的80%以上，接近于电晕临界电场强度，而新架设导线表面的局部污损又导致导线电晕临界电压降低，故运行初期和在雨天情况下仍难免出现电晕。相导线上产生电晕放电时，要伴随着产生连续重复性的电流脉冲，这些电流脉冲产生频率为0.15~100 MHz的振荡电磁波，致使在电晕导线上产生高频电磁辐射，从而在导线周围形成一高频电场，对无线电收音机和发射天线产生干扰。同时这种振荡电磁波还沿导线传播，干扰高频通道的正常工作. 由电晕导线产生的无线电干扰电平L-20 19(EZ/E，)，dB。其中EZ为测点电场强度，拌V/m;E，为参考电场强度，拌V/m。工程上取E，一1拌V/m为基准，故L~20 lgEZ。若EZ~El~1拜V/m，则测点的无线电干扰电平为零。 从高压、超高压架空输电线路下测得的无线电干扰电平L(dB)随频率f(MH:)的增大而减弱，其关系曲线称为频谱特性，如图2所示。由频谱特性看出，频率在0.15~1.0 MH:范围内的干扰电平最大;雨天的干扰电平是各种气候中最大的。另外，随着海拔高度的增大，相对空气密度减小，干扰电平也增大。
