Surge and lightning protection for gas pressure control and measurement systems

Gas pressure control and measurement systems are essential for the safe distribution of natural gas. They ensure optimum pressure, measure flow rates and maintain grid stability – often in challenging conditions and in potentially explosive atmospheres. 

Protection against overvoltage and lightning strikes is therefore essential. 

With innovative and proven protection solutions, practical planning tools and expert advice, we're by your side as a trusted partner. Find out here how a comprehensive, standard-compliant protection concept can safeguard your system against failures, malfunctions and safety-critical incidents. 

Why gas pressure control and measurement systems are particularly vulnerable

The combination of mechanical gas pressure control technology, sensitive measurement instrumentation, control systems, communication, and remote telemetry makes GDRM stations susceptible to lightning and surge effects. Direct or nearby lightning strikes, as well as switching operations in the grid, can generate overvoltages that enter the system via power, measurement, control, and data lines.

Typical risks:  

  • Damage to sensitive components such as pressure sensors, flow meters, gas chromatographs, or control systems
  • Incorrect measurements, data loss, or disruptions to remote telemetry
  • Faulty pressure regulation or incorrect billing data
  • Automatic shutdowns and unplanned service interventions
  • Impairment of safety-related systems
  • Sparking, hazardous potential differences, or ignition risks in hazardous (Ex) areas

Even short-duration overvoltages can compromise the operational safety of a GDRM station and affect the supply of entire network sections. A coordinated lightning and surge protection concept protects sensitive equipment, reduces failure risks, and ensures a reliable gas supply in the long term.
