Commerce trade and industry, national and local institutions, and the private household as well depend to an ever increasing extent on electronic equipment and information technology systems.
Failures of such highly sensitive systems are frequently caused by electrostatic discharges, switching overvoltages or overvoltages due to lightning strikes. Damage caused, in particular, by thunderstorm overvoltages have shown in the past years that electronic systems are at risk through electromagnetic fields and line-fed overvoltages at a distance of up to 1.5km from the point of the lightning strike.
History
At first there was the idea of
diverting lightning to the
ground without endangering
home or people. This was the
challenge, Hans Dehn met in
his company founded in
Nuremberg in 1910. Since the
beginning of the 1920s DEHN
has produced lightning protection
and earthing components.
Over the years, a diversified
product range for external
lightning protection came into
existence.
However, not only protecting
systems and buildings against
the effects of lightning, but also
the protection of people
installing and maintaining electrical
systems became a central
requirement.
In 1952, DEHN & SOHNE amplified
their product range by
safety equipment for working
in electrical installations.
The entering of electrical and
electronic equipment in industries,
administrations and
households showed soon, that
conventional lightning protection
was not sufficient to protect
these devices. With the
experience of decades in the
field of external lightning
protection, the necessity of
surge protection came up.
Therefore, the first generation
of surge protective devices
(SPDs) of DEHN & SOHNE was
introduced to the market in
1954.
Today, DEHN & SOHNE produce more
than 3,500 devices and components
for your safety.
DEHN & SOHNE is a worldwide
recognised and leading family owned
company.
