From Reaction to Prevention

Lightning forms when the electric field between cloud and ground crosses a critical threshold. Euthalia’s system—using Air Heads, filters, and field stabilizers—continuously conditions the local electromagnetic environment to keep the field below that threshold in the protected volume. Result: a dramatic drop in the probability of a lightning leader forming nearby.

Traditional vs Euthalia:

Aspect	Traditional Rods/Downconductors	Euthalia Preventive System
Core idea	Provide a low-impedance path after a strike	Stabilize and lower local field to avoid strike initiation
Impact on assets	Strike still occurs; energy & surges to manage	Greatly reduces strike formation in vicinity
Uptime	Needs robust SPD & bonding to manage surges	Fewer surge events → higher uptime
Coverage	Point protection; relies on geometry	Volumetric protected area (engineered per site)
Lifecycle	Periodic inspection/earthing checks	Engineered system + monitoring, AMC

Standards note (short, factual):
Design and risk assessment follow IEC/EN 62305 lightning protection principles for site assessment, external/internal LPS and surge coordination. Euthalia’s approach complements the standard’s risk-based methodology while introducing a preventive field-stabilization layer. ABB Library
