Safety concepts
Surges - an often underestimated risk
Protection against potential consequences of a thunderstorm is a must in our highly sophisticated world.
What if operation stands still?
Without protection, a company can quickly roll out of play. The effects of
a thunderstorm can paralyse EDP systems.
Consequently, customers of an affected company cannot be served for a longer
period of time. For the hotly contested automotive industry, for example,
this would be disastrous. Just-in-time deliveries for the automotive
industry are nearly impossible in case of such a breakdown. This can even lead
to a dramatic fall of the share price of the affected company.
Therefore,
the most important consequence is:
Prevent damage caused by surges!
What are surges and how do they come into existence?
Surges are short-time voltage impulses - so called transients - coming up only for some split seconds. Every company has more than enough sensitive targets for these destructive transients:
- power supply
- EDP system
- control system of producing facilities via field bus
- telephone system
- regulation of the air-conditioning system
- lighting control
Safety can be achieved
These sensitive systems can only be protected by a comprehensive protection
concept. Cascading the protection is important here.
For this purpose, lightning current and surge arresters are used. Lightning current
arresters conduct high energies without damage. Surge arresters protect terminal
equipment. Lightning current arresters have to be installed as closely as possible
to the service entrance of the electrical system and surge arresters near
the equipment to be protected.
With their product families 
Red/Line and Yellow/Line DEHN + SÖHNE provides
coordinated surge protective devices (SPDs). This modular system allows for
cost-effective realisation of lightning and surge protective concepts for all
industrial branches, service companies, and sizes of installations.
