Abstract : Sensitive electronic systems are shielded against electromagnetic interferences (lightning, EMP). The shielding efficiency is reduced by field coupling through apertures and particularly by feeding of interfering currents through cable entries. In case these cables are connected to the inputs of electronic devices, the surge voltages may disturb or even destroy these devices or single electronic components, particularly semiconductors. Special passive protection circuits for communication and power lines against lightning- and EMP-induced surge voltages are developed. The edge steepnesses of the applying surge voltages show values of 2kV/us (lightning) up to 2kV/ns (EMP). (Author)
