Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method
High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐
