The aim of an external lightning protection system is to protect buildings from direct lightning strikes and fire or from the effects of lightning current.

In this web-based training course you will become familiar with the air-termination system, down conductor and earth-termination system of an external lightning protection system and you will learn how to plan an external lightning protection system.


Lightning strikes are the main source of surges and jeopardise buildings and installations even if they are protected by a lightning protection system.

Our power supply, communication and information systems are based on sensitive electric and electronic devices.
If these components fail or malfunction, entire systems come to a standstill and the consequences are far-reaching.
It is therefore important to prevent damage to devices, installations and systems.

Lightning and surge protection are vital elements here.


In Germany alone, there are 2 million lightning flashes a year! This figure really brings home the danger.

Many people do not realise that not only a direct lightning strike to the building is dangerous. Electric devices can be damaged in a radius of up to 2 km from the point of strike.

Make residential buildings safe with the help of a comprehensive protection concept.

The DEHN Risk Tool - Risk Management allows you to determine the risk potential of the structure and to find the right class of LPS for your building.

In addition to theoretical principles of risk management, this training course shows how to use the DEHN Risk Tool based on an example.

This course is the ideal preparation for the DEHNsupport seminar and a good way of familiarising yourself with the basic use of the DEHN Risk Tool.
