Surge Protection Systems

Surge Protection and an underestimated risk

This system consists of external lightning protection and internal surge protection. This

The purpose of an external lightning protection system

• Use of an air-termination system to intercept direct lightning strikes
• Down-conductor system used to safely discharge a lightning current
• Earth-termination system distributes the lightning current in the ground

Elements of surge protection systems

• Separation distances
• Earth-termination system
• Down conductor
• Lightning equipotential bonding (interconnecting all isolated conducting parts of the installation by means of surge protective devices)
• Air-termination systems
