Working Principle
The system generates controlled high-current pulses that replicate different stages of a lightning strike. Each component (A, B, C, D) represents a specific phase of lightning discharge, including initial high-current peaks, intermediate currents, and long-duration continuing currents.
By applying these currents in sequence, the system simulates real lightning events, allowing evaluation of material behavior, thermal effects, and structural integrity under extreme electrical stress.
