Abstract: With the further development of UHV AC transmission lines in China,transmission corridors are increasingly tense,and it is increasing common for residents to live and work near the transmission line. When the human body contacts metal objects such as steel frame shed under the line,it is easy to produce transient electric shock,which causes troubles and unhappiness to the nearby residents. In order to study the suppression method for it,a 1000 k V double circuit transmission line on the same tower,an underground shed and a human body model were established to calculate the induced potential and discharge current of human body when the transient electric shock occurred,and the effect of different suppression measures were analyzed. The results show that the characteristic value of transient electric shock increases with the improvement of human insulation performance. In the scenario as described in the paper,the peak value of discharge current can reach 0.14 A. Setting up shielding wire,shielding net and planting trees can reduce the discharge current by 65%,80.7% and 96.8%respectively. In the actual scene,specific measures should be taken according to the electric field shielding requirements and site conditions.
