Abstract :
Transmission line arresters may be subjected to high energy stresses caused by lighting. Calculations of energy stresses were carried out for a typical line arrester installation. Three line configurations with different degrees of shielding efficiency were used for the study. The primary statistical parameter was the charge of the flash, including multiple strokes. The effect of stroke current magnitude was also investigated. The calculated results were compared with energy stresses in standardized tests on surge arresters
