Direct and Indirect Effects
Direct Effects
Direct effects of lightning is burning, eroding, blasting
and structural deformation caused by a direct arc attachment
to the vehicle, facilities and/or shipping containers.
Structural damage effects typically occur in the immediate
area of the
lightning
model since that is where the current density is the
highest. As lightning current enters a conductive structure,
it rapidly spreads so that current density is quickly reduced
to harmless levels. Damage may be extensive if current
dispersion is prevented or if there is limited
current-carrying capacity in the path taken by the lightning
current.
Indirect Effects:
Indirect effects of lightning refers to the damage to or
malfunction of electrical equipment that results from a nearby
lightning flash. These effects may range from tripping a
circuit breaker, to computer upset, to physical damage to
input or output circuits of electronic equipment.
