Protection against lightning - Electrical and electronic systems within structuresThe need for BS EN 62305 4: 2006 has arisen due to the increasing cost of failures of electrical and electronic systems, caused by electromagnetic effects of lightning. Permanent failure of electrical and electronic systems can be caused by the lightning electromagnetic impulse (LEMP) via: a) conducted and induced surges transmitted to apparatus via connecting wiring b) the effects of radiated electromagnetic fields directly into apparatus itself.
