Internal lightning protection

Your home’s lightning protection system directs lightning to the ground and prevents direct lightning strikes from causing damage or fire. They are commonly found on tall buildings, towers, and masts. Lighting protection systems are made up of external lightning protection (lightning protection/earthing) and internal lightning protection (surge protection). By reducing the potential difference between lightning currents, lightning equipotential bonding can reduce the effects of lightning. Since lightning strikes are such a common phenomenon, your house may also be struck by lightning at some point.

Internal lightning protection systems should include an adequate overvoltage protection installation as well as other methods to minimize the destructive effects of lightning (equipotential bonds, shields, etc.). Even though transient overvoltages can occur from a variety of sources, lightning is the most destructive. Power lines, telephone lines, television and data supply lines can introduce short-lived voltage surges to electrical equipment. Safety incidents can be reduced to an acceptable level for people and property by overvoltage protection. When electrical signals are normal, surge protection devices remain inactive, but respond instantaneously to transient surge peaks by conducting lightning currents to earth and protecting equipment. Overvoltages can take the following forms:

  • Internal lightning protection are installed in places where lightning currents and electromagnetic effects of lightning are not attenuated (main switchboards) in order to protect against direct lightning strikes.
  • Protection against secondary effects of lightning in places where lightning currents and electromagnetic effects are already attenuated (secondary frames).
  • Protects against overvoltages that are already much damped, leaving very little residual voltage. Normally, they are installed near the sensitive equipment.

With the rapid advancement of technology, our society has become increasingly dependent on Internal lightning protection systems. Both the threat of damage to critical electronic systems, as well as the seriousness of the consequences, have increased in recent years. In the event of their loss, commercial, governmental, and industrial organizations would all be crippled. There are many modern electronic systems that could be damaged:

  • Computers
  • Data communication networks
  • Building management systems
  • CCTV equipment
  • alarms
  • Uninterruptible power supplies (UPSs)
  • Programmable logic controllers (PLCs)
  • Smart Sensors
