Induced voltage due to lightning strikes near overhead distribution lines — Focus on discharge currents based on measurements in Brazil and Switzerland

Abstract

This study investigates the impact of lightning strikes on power transmission systems, focusing on indirect events near distribution lines. The incidence of these strikes can result in line outages, significantly affecting system reliability. To address this phenomenon, we propose a methodology based on the finite element method in the time domain. Results obtained from implementing this methodology reveal differences of up to 44% in terms of induced voltage between Morro do Cachimbo and San Salvatore data. Such results emphasize the importance of carefully considering the effects of lightning strikes to enhance the resilience and reliability of electrical power systems.
