Summary: A numerical model was developed to analyze lightning attachment on UHV-AC double-circuit transmission lines. Simulation results showed that upward leaders simultaneously occurred on the ground wire and the upper-phase conductor when the phase conductors were energized. A new expression for calculating the striking distance on the ground wire was proposed based on the simulation results. Additionally, high voltage, phase angle, and terrain slope were found to increase the surface electric field of the upper-phase conductor.
