Title:
FLUID TURBINE LIGHTNING PROTECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/040361
Kind Code:
A3
Abstract:
A fluid turbine lightning protection system includes at least one air termination device, formed at least in part of an electrically conductive material, that can be positioned on a shroud of a fluid turbine and placed in electrical communication with a down conduction system. The down conduction system is in electrical communication with an earth-termination system configured to dissipate electricity transferred thereto to the ground. The at least one air termination device is configured to intercept a lightning strike and direct it through the down conduction system, the earth-termination system, and into the ground. The at least one air termination device may be positioned on a turbine shroud based on a "Rolling Sphere" derivation wherein the "Rolling Sphere" derivation is derived from the equation r = 10 · I0.65, where I is the peak current in kiloamperes and r is the rolling sphere radius in meters.
