Poznámky redaktora
Surge voltages interfere with destroy electrical and electronic systems.Danger: surge pulse due inductive and galvanic coupling S2: Lightning strike near building and couplings over radius km A local lightning strike creates additional high magnet- ic fields, which turn induce high voltage peaks in cable systems. Inductive galvanic couplings can cause damage within radius around the lightning impact point. A local lightning strike creates ad- ditional high magnetic fields, which turn induce high voltage peaks cable systems. Lightning and surge protection devices protect against uncontrolled arcing (sparks) and the resulting fire risk.
