| Abstract: | When the breakdown of substation frame or tower in transmission lines occurs in single-phase or interphase short circuit and grounding,grounding potential will rise,then possible step and touch potential will endanger personal safety.According to the measure and analysis of step and touch potential of 4th iron tower for 110kV Xinqian transmission line,corresponding countermeasure is presented and probable grouding risk is appraised in the paper. |
