How does a train strike lightning?
Direct lightning (direct lightning), that is, what we usually call lightning. Direct lightning has three major effects of thermal effect, electrical effect and mechanical effect, and the lightning energy is huge, which can cause physical damage and electric shock damage to the object, such as breakage, collapse, etc..
Lightning, lightning formation process, because the thundercloud charge in the accumulation, and the lightning occurs when the lightning cloud charge decreased sharply and will form a wide range of electrostatic and electromagnetic induction phenomenon, resulting in the effects of lightning range (lightning radius 2Km) metal conductor high potential (high voltage) and the impulse current (surge). The main harm may be caused by the potential difference between adjacent conductors to produce electrical sparks, surge, resulting in power and signal line breakdown phenomenon, resulting in short circuit, and invasion of electrical equipment, resulting in damage to equipment. Especially for low voltage electrical systems and electronic information systems.
Because the train is on the track, and the track is very long, the equivalent of good grounding conductor, so the train is actually the entire body is grounded, not afraid of lightning.
