| Abstract: | The grounding devices of the transmission line towers are not able to meet the requirements on condition of lighting. The characteristics of impulse grounded resistance of various grounded devices were analyzed. The relationship between the impulse grounded resistance and the lightning current waveform, the relationship between the soil resistivity, and the length of radial conductor were given. Some grounded devices suitable for transmission line tower were also put forward. |
