Mobility

Electric and electronic systems in railway technology and e-mobility are becoming more and more sensitive. The fact that components are becoming increasingly interdependent and expectations with regard to reliable functionality are growing, speaks in favour of a comprehensive protection concept.

 

Railway infrastructure

Avoid system downtime and disruptions in the railway infrastructure

The smooth running of railway technology depends on the proper functioning of a variety of highly sensitive, electric and electronic systems.

The permanent availability of these systems is, however, threatened by lightning strikes and electromagnetic interference. As a rule, damaged and destroyed conductors, interlocking components, modules or computer systems are the root cause of disruptions and time-consuming troubleshooting. This, in turn, means late trains and high costs.


Reduce costly disruptions and minimise system downtime... with a comprehensive lightning and surge protection concept tailored to your special requirements.

Reasons for disruptions and damage

These are the most common reasons for disruptions and damage in electric railway systems:

  • Direct lightning strikes
    Lightning strikes in overhead contact lines, tracks or masts usually lead to disruptions or system failure.
  • Indirect lightning strikes
    Lightning strikes in a nearby building or the ground. Overvoltage is then distributed via cables or inductively induced, damaging or destroying unprotected electronic components.
  • Electromagnetic interference fields
    Overvoltage can occur when different systems interact due to their proximity to one another, e.g., illuminated sign systems over motorways, high-voltage transmission lines and overhead contact lines for railways.
  • Occurrences within the railway system itself
    Switching operations and triggering fuses are an additional risk factor because they can also generate surges and cause damage.

E-mobility

Protect the charging infrastructure and electric vehicles from lightning and surge damage

Electric vehicles - clean, fast and quiet - are becoming increasingly popular. Being involved right from the start is important in many sectors.

The quickly growing e-mobility market is sparking great interest among the industry, utilities, communities and citizens. To be in the black as soon as possible, it is vital to prevent downtime. Therefore, a comprehensive lightning and surge protection concept must be implemented already at the design phase.

Two key aspects to be considered

Talking of protection there are two main issues that have to be taken into account:
Facilities and human life.
