  • Isolating spark gap
    Isolating spark gap

    The FLT-ISG… isolating spark gap for protecting insulating flanges on pipelines and indirect equipotential bonding

  • Lightning current measuring
    Lightning monitoring

    The lightning monitoring system acquires and analyzes lighting surge currents. Maintenance can therefore be planned optimally.

  • Interference filters
    Interference filters

    Interference filters limit unwanted voltage peaks and smooth the voltage signal.

High-frequency, low-energy interference can be smoothed and eliminated using interference filters. Meanwhile lightning and surge protective devices provide protection against transient and high-energy voltage peaks.

Your advantages

  • Protection for all common applications and signals, thanks to the complete product portfolio
  • Versatile fields of application – designs and connection methods for every application
  • Space-saving and inexpensive installation, thanks to slim design
  • Easy testing, thanks to plug-in arresters
  • Protection against transient and high-frequency voltages with combinations of interference filters and surge protection

The protective circuit principle

The protective circuit provides seamless protection against surge voltages.  

The protective circuit against surge voltages

An "effective protective circuit" helps to implement seamless surge protection.

And this is how it works:

Draw an imaginary circle around the object you want to protect.

Surge protective devices must be installed at all points where cables intersect this circle.

The area within the protective circuit is therefore protected in such a way that conducted surge voltages are prevented.

Consider the following areas during planning:

  • Power supply
  • Measurement and control technology
  • Data processing, telecommunications
  • Transceiver devices
