Overview current standards:
• Internal lightning protection
IEC 62305-4
• Surge protection
IEC 60364-5-53
Surge protection devices increase the

Surge protection through equipotential bonding
If electrical devices are subjected high potential
difference surge voltage, then the insulation the
voltage resistance may exceeded. These voltage peaks can
penetrate building though all manner conductive
connections and cause enormous damage.
Current statistics and estimates insurance compan-
ies show: damage levels caused surges exclud-

reached drastic levels due the growing dependency
on electronic devices. Sensitive databases, e. Like bird a

Our dependency electrical and electronic equip-

Surge protection part the equipotential bonding

During thunderstorms too, high volumes energy are
