Surge arresters protect electrical equipment from overvoltages caused by incoming surges. Overvoltages can be caused by direct or indirect lightning strikes, electromagnetic pulses, electrostatic discharges, or device switching. Some overvoltages are very powerful. The surge current is diverted through the arrester, usually to earth. Depending on the application, different surge arrester types are needed for effective overvoltage protection.
Railway Surge Arrester
Reliable, stable, and safe overvoltage protection
In railway systems, Siemens Energy surge arresters help make sure that lightning overvoltages do not result in damage to the insulation in system components and the traction vehicles themselves. Surge arresters meet all worldwide requirements for the overvoltage protection of rail vehicles and electrification. The comprehensive portfolio makes it possible to find the ideal surge arrester for any conceivable application and meet even specific demands, such as:
• high mechanical stability to withstand vibrations and high wind speeds
• extremely reliable pressure relief behaviour when special protection is required
• excellent pollution layer characteristics for coastal and desert regions and areas with extreme air pollution
Standards and testing – reliability you can count on
Siemens Energy surge arresters for rail applications comply with the latest versions of
• IEC 60099-4, Metal-oxide surge arresters without gaps for AC systems
