A Lightning Rod Protects the Structure.
Surge Protection Protects What’s Inside.
A lightning rod safeguards building masonry, but lightning-induced electromagnetic pulses (LEMP) and switching surges travel miles through electrical and communication lines. Surge Protection Devices (SPDs) restrict transient voltages to safe clamping levels within nanoseconds.
How Progressive Energy Attenuation Works
Transient overvoltages traveling along incoming utility lines or induced from nearby strikes are clamped step-by-step:
Service Entrance Lightning Current Arrester
Discharges direct high-energy partial lightning currents entering through overhead utility cables before they penetrate downstream distribution.
Sub-Distribution Surge Arrester
Clamps induced switching overvoltages and secondary transients to moderate residual voltage levels across building sub-circuits.
Terminal Equipment Surge Suppressor
Fine voltage attenuation safeguarding microprocessors, audio-visual equipment, and medical devices from residual millivolt spikes.
