Abstrakt

In this chapter, the basic concept of lightning shielding analysis of overhead transmission line using conventional electro-geometric (EGM) method is presented. Since the conventional EGM method is not applicable for the fully composite pylon, therefore, the conventional EGM is modified to be used for the assessment of lightning shielding performance of the pylon. The shielding failure rate (SFR) and shielding failure flashover rate (SFFOR) of the fully composite pylon with a preliminary assigned shielding angle of −60° are calculated using the modified EGM method for the vertical lightning strikes. The lightning shielding behavior of fully composite pylon against possible horizontal lightning strikes is also investigated using rolling sphere method (RSM).
