Based on the lightning protective experiments of automatic weather stations, the characteristics of lightning induced voltage in power cables with different burying situations are analyzed.The results show that soil has significant shielding effect on LEMP (Lightning ElectroMagnetic Pulse) of return strokes. Compared with the peak lightning induced voltage in the power cable on the ground, the peak value of the induced voltage under the depth of 05 meters is 522%. The induced voltage shows an oscillation waveform with a tendency of attenuation. At the same time, the induced voltages of buried power cables show a smaller amplitude in the frequency from 50 kHz to 5 MHz. The decreasing in the frequency from 9055 kHz to 1535 MHz is more obvious.
