Abstract
The current situation of Hunan high voltage transmission lines is introduced in this paper. Statistical results
based on the recent years of transmission line faults
show that the main reason for the transmission lines trip are the lightning
contamination and outside-force destroy. The lightning trip rate of transmission lines is calculated and analyzed. The causes of lightning-stroke
contamination-spark and their preventing measures are investigated in this paper.
