Surge protection

Power surges or transient overvoltages can be caused in two ways: either as the secondary effect of a lightning strike (up to a kilometre away), or by the electrical switching of large inductive loads (such as motors and transformers).

They may last less than a millionth of a second but they are powerful and potentially highly destructive causing:

  • disrupting system operations
  • degrading equipment components
  • destroying components and circuit boards, and surge protection
  • causing costly and unnecessary downtime

Thor can supply and install effective protection from surges with the Furse ESP maintenance free range of voltage protectors ideal for use with: 

  • mains power supplies
  • data and telecoms equipment
  • computer networks
  • RF, CCTV, rail and CATV systems
