If lightning strikes a structure or the ground close-by and that structure has electrical cabling connecting it to another structure further away, the increase in voltage at the point where the lightning strikes, will cause current to flow down the cable. This can cause damage to equipment at both ends of the cable.
The first and most important stage of protection is a surge diverter located inside the main electrical switchboard. Surge diverters direct to earth most of the energy of a surge or spike at the point of entry to a building or major power distribution point.
The next stage of power line protection and an absolute must is a surge diverter located in the main switchboard. The third stage of protection for electronic equipment is a surge filter for each electronic device, the filter is located either inside the power distribution board where the electronic equipment derives its power or connected into a general-purpose power outlet.
As a voltage surge can occur at either end of a signal or data cable causing electrical current to flow in either direction, it is necessary to protect electronic equipment at both ends of the cable.
A typical example of a complete lightning and surge protection.
