A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth.

Applications

  • Protection of AIS and GIS substation equipment
  • HVDC protection
  • Protection of series capacitor banks
  • Protection of cables
  • Protection of transmission lines
  • Polluted areas and areas with high seismic activities
