A Complete Lightning Protection System consists of two essential components.
An effective and compliant protection installation requires a holistic approach.
While external protection safely manages the energy from a direct strike, internal surge protection shields sensitive electrical and electronic systems from damaging transient voltages.
SME delivers both elements as a fully coordinated solution, helping you reduce risk, prevent downtime, and protect assets.
External
Lightning Protection System (LPS)
Designed to safely intercept a lightning strike and direct its energy harmlessly into the ground before it can damage the structure or endanger occupants. By providing a controlled path for lightning current, it helps protect the building, critical assets, and the people inside.
The system consists of three key components:
-
Air Termination System (ATS) Captures and intercepts direct lightning strikes.
-
Down Conductor System (DCS) Safely carries lightning current from the roof level to ground level.
-
Earth Termination System (ETS) Dissipates lightning energy safely into the earth.
Internal
Lightning Protection System (LPS)
Designed to manage dangerous surge energy and eliminate hazardous voltage differences within a structure. By protecting electrical installations, electronic equipment, data networks, and personnel from the indirect effects of lightning, it helps ensure operational continuity and reduces the risk of equipment damage and downtime.
The system consists of three key components:
-
Surge Protection Devices (SPDs) Limit transient overvoltages and protect sensitive electrical and electronic equipment.
-
Equipotential Bonding Connects conductive services and systems to maintain the same electrical potential and reduce the risk of dangerous voltage differences.
-
Separation Distance Management Prevents flashover between the lightning protection system and internal conductive elements.
