Chapter General introduction
. Particularly
when production plants, lighting systems trans-
formers are switched off, electrical equipment located
in close proximity can damaged. Switching surges are additionally
caused switch-on and switch-off operations, the
switching inductive and capacitive loads, and by
the interruption short circuit currents.Danger: galvanically coupled and line-carried surge voltage
S4: Direct lightning strike supply line
The proximity the lightning strike induces surge
voltages cables
