STAGE III : Lightning Protection Bacis

LIGHTNING TYPES
Far from uniform, lightning is an unpredictable phenomenon

» Staccato Lightning : Common
A heavily branced cloud-to-ground lightning strike with short duration strike and incredibly bright flash.

» Sheet Lightning : Common
A generic terms used to describe types of cloud-to-cloud lightning where the discharge path of the strike is hidden from view, causing a diffuse brightening of the surrounding clouds in a sheet of light.

» Megalightning : Frequent
A term commonly used when referring to upper-atmospheric types of lightning. These include sprites, blue jets and elves and occur in the strastophere and thermosphere.

» Bead Lightning : Rare
A type of cloud-to-ground lightning where the strike seems to break up into smaller, super-bright section (the beads), lasting longer than a standard discharge channel.

» Ribbon Lightning : Quite rare
Only occuring in storms with high cross winds and multiple return strokes, ribbon lightning occurs when each subsequent stroke is blown to the side of the last, causing a visual ribbon effect.

» Ball Lightning : Very rare
Considered as purely hypothetical by meteorologists, ball lightning is a highly luminous, spherical discharge that according to few eyewitnesses last multiple seconds and can move on the wind.

A clip from Discovery Channel's "Raging Planet" on the subject of lightning. If you find lightning a facinating and beautiful force, then check this clip out. The camera technology has gotten to where scientists have been able to record and playback a lightning strike at over 200X slower with really cool results.

Lightning Protection Design Basic
» Air Termination systems : Rolling Sphere Radius, Mesh Size and Protection Angle
» Down-conductor systems : Connections from Air Termination Systems to Earth-termination systems
» Earth-termination systems : Conductor that are intended to disperse lighning current into the earth

Others
» Fixing and connections : Accesories
» Materials and Dimensions : Standard Conductors

Air-termination system
Part of an external LPS using metallic elements such as rods, mesh conductors or catenary wires which is intended to intercept lightning flashes.

Down-conductor system
Part of an external LPS which is intended to conduct lightning current from the air-termination system to the earth-termination system.

Ring conductor
Conductor forming a loop around the structure and interconnecting the down-conductors for distribution of lightning current among them.

Earth-termination system
Part of an external LPS which is intended to conduct and disperse lightning current into the earth.
