DEHN protects.

The powerful natural phenomenon of lightning and

thunder has fascinated mankind through the ages. In

Greek mythology Zeus, the Father of Gods, is seen as

the dominion of the sky whose power is often envi-

sioned as a lightning bolt. The Romans attributed this

power to Jupiter while the continental Germanic tribes

to Donar, known to the North Germans as Thor. For a

long time, the enormous force of a thunderstorm was

associated with a supernatural power and humans felt

at the mercy of this power. Since the Age of Enlight-

enment and the advancement of technology, this

heavenly spectacle has been regarded more soberly. In

1752, the kite experiment by the inventor and states-

man Benjamin Franklin demonstrated that the phe-

nomenon of lightning is in fact a form of electricity.

Nowadays, we are better able to understand and

explain the causes of thunder and lightning. And

although this natural phenomenon is fascinating to

watch, it is also extremely dangerous.

Lightning: Fascinating to watch, but also extremely dangerous

2

Every year, lightning kills people and animals and

destroys material assets. Most of these fatal conse-

quences, however, could be prevented by taking

appropriate protection measures.

Thunder and lightning in times of climate change

Increasingly extreme weather: Meteorological data

show that thunderstorms are on the rise globally, even

in the moderate European climate. In Germany alone,

more than two million lightning strikes are recorded

every year and the tendency is rising. Severe thunder-

storms threaten lives and cause great damage: Hail

destroys roofs and cars. Lightning strikes cause fire and

surge damage to electrical or electronic devices and

systems – or even destroy them completely. Lightning

strikes have particularly fatal consequences for the

industry, power generation or infrastructure sector:

System failures and production downtimes result in

substantial financial loss while failure of fire alarm sys-

tems or emergency centres can cause serious personal

injury or even death.

Lightning protection from DEHN

In 1910, the electrician and precision engineer

Hans Dehn set up an electrical installation company

in Nuremberg. After Hans Dehn had successfully

completed his training as a state-registered installer

of lightning protection systems, the installation of

such systems became an integral part of the young

company right from the start. Fascinated by external

lightning protection, Hans Dehn came up with his

first invention in 1918 and registered his first patent.

Further patents followed in the course of the com-

pany’s history.

Unique test laboratory

Our renowned impulse current laboratory is integral for

the successful development of new products, systems and

protection concepts: Here we are able to test protection

functions with lightning currents up to 200 kA (10/350 µs)

under realistic conditions. For many years, we have been

studying the characteristics of natural lightning strikes in

detail on a lightning measuring station in Austria where

natural lightning strikes are analysed and the phenomenon

of lightning is investigated. From the results of this funda-

mental research, conclusions are drawn for product devel-

opment, standardisation and tests in our test laboratory.

Most stringent quality standards worldwide

Our aim is to ensure optimum quality. For our products we

use only high-quality materials, we carry out all production

steps in-house, and we inspect all finished products before

they leave our premises. Our products and systems comply

with the applicable standards. Products for the interna-

tional market are manufactured in line with country-specific

standards. Our manufacturing processes are certified to the

DIN EN ISO 9001 standard. All these standards allow us to

offer our customers safe, reliable and durable products and
