Abstract
A system is provided for dissipating electrical charges that build on a rotatable shaft extending from an electrically-grounded motor housing or rotating shafts conductively linked to components that create and electrical charge, such as wind turbine blades, power generator turbines, and the like. The system includes a frame defining a central opening wherein the rotatable shaft is positioned with the central opening, a first grounding fiber secured within the frame, and a fiber clamp positioned with the frame. The fiber clamp acts to urge the first grounding fiber toward the central opening. The system may also include a mounting bracket having a frame mounting channel, wherein a portion of the frame is securely retained within the frame mounting channel, and an installation guide positioned on the mounting bracket. The installation guide may be configured to properly align the frame and the first grounding fiber relative to the rotatable motor shaft.
