SUMMARY
Lightning induces voltage spikes in power lines primarily through the electromagnetic fields generated by the lightning current, which creates an electromotive force (emf) in the lines. This phenomenon is characterized by high-frequency alternating current (AC) that oscillates in both directions, leading to potential voltage spikes. The discussion clarifies that the emf produced by lightning cannot cancel the emf of a generator, as the nature of the induced voltage is fundamentally different. Understanding these principles is crucial for designing effective lightning protection systems.
