Research on Reduced Scale Experiment of Induced Overvoltage on Distribution Line

Abstract:

Lightning is one of the most important reason of outage of distribution line. And nearly 90% of the accidents of lightning failure is result of lightning induced overvoltage. In order to protect the distribution line from lightning, it is required to have a comprehensive understanding of characteristic of lightning induced overvoltage. Due to the advantage of reduced scale experiment, which are controllable and practical, the characteristic of lightning induced overvoltage is got from it. Comparing the results of experiment with the results of calculation, it is found that changes of overvoltage with height and distance match well with the calculated results, which show that the reduced scale experiment is effective and proper.
