Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor with the current density being largest near the surface of the conductor, decreasing at greater depths. The electric current flows mainly at t

考虑到集肤效应和土壤电阻率对架空线路频变参数的影响后，编写程序以计算阻抗。(Considering the influence of skin effect and soil resistivity on the frequency variation parameters of overhead lines, a program is compiled to calculate the impedance.)
