Protect lives and investments, and increase system availability

Digitalization is everywhere – on condition that the power flows. Without a reliable power supply, plants, machinery, and buildings cannot be operated, and data processing for analysis, operation control, automation, and many other functions is not possible. For a secure power supply, it is absolutely necessary to prevent arc faults, or to detect and quench arc faults. Even though they occur very rarely, such events can cause serious damage. In this context, well thought-out concepts and solutions provide the best protection for people, data, and assets.

 

As an additional part of the protection concepts, arc protection systems can considerably reduce the arc fault effects. Best possible protection is only provided if the individual components and systems of the electric power distribution are integrated in an overall solution, because:

 

• Priority 1 is protection of persons

• Priority 2 is service continuity, including protection of the surroundings and the environment

• Priority 3 is protection of equipment and property

 

When human health and life are at risk, precaution is always a good advisor – and when electric power in the form of an arc fault can be detected, speed is the key.
