Surge protection through equipotential bonding
If electrical devices are subjected high potential
difference surge voltage, then the insulation the
voltage resistance may exceeded. Surge protection devices (SPDs) are, like
an open switch, connected the equipotential bond-
ing and safely short circuit the surge voltage before a
destructive failure the insulation.g. Sensitive databases, e.
It not only lightning strikes that pose latent threat
to these systems.
Overview current standards:
• Internal lightning protection
IEC 62305-4
• Surge protection
IEC 60364-5-53
Surge protection devices increase the

Our dependency electrical and electronic equip-

During thunderstorms too, high volumes energy are
instantaneously released. Ever more frequently, today's elec-
tronic devices are damaged surge voltages caused
by remote lightning discharges switching opera-
tions large electrical systems. It's surprise, then, that prop-
erty insurers are checking more and more claims and
stipulating the use devices protect against
surges. This destroys
the device.
Current statistics and estimates insurance compan-
ies show: damage levels caused surges exclud-
ing consequential outage costs long since
reached drastic levels due the growing dependency
on electronic devices.
Internal lightning protection systems and surge
voltage protection concepts are covered current
standards and meet the very latest requirements.
