It's surprise, then, that prop-
erty insurers are checking more and more claims and
stipulating the use devices protect against
surges.
Internal lightning protection systems and surge
voltage protection concepts are covered current
standards and meet the very latest requirements. Like bird a
high tension line, the electrical device raised a
single potential and thus protected. Sensitive databases, e.
It not only lightning strikes that pose latent threat

penetrate building though all manner conductive
connections and cause enormous damage.
During thunderstorms too, high volumes energy are

Surge protection through equipotential bonding
If electrical devices are subjected high potential
difference surge voltage, then the insulation the
voltage resistance may exceeded. the Directive VDS 2010 (German

Surge protection part the equipotential bonding

short circuit and risk fire. Ever more frequently, today's elec-
