Lighting performance study on existing 275KV overhead line in TNB system
Lightning is the primary cause of tripping for most overhead power transmission lines. Few methods have heen discovered to estimate the lightning performance of a transmission line. However these methods are not properly defined due to the nature of lightning which is difficult to analyze and model....
