Wind turbines require accurate and reliable blade pitch-control to optimize wind generation and safeguard the asset from extreme conditions that could cause damage. Turbine generators also rely on precise feedback to properly control and synchronize energy output with line frequency. Disruption of these processes can lead to poor turbine performance, downtime, or costly repairs. Encoders…

As the nacelle of the turbine rotates into the wind, a slip ring prevents the cables from twisting into a knot.

By May 2016, UEA’s monthly PPM had dropped to 1,380.

Jesse Shearer | Design Engineer | United Equipment Accessories As the wind energy industry has grown over the last decade, so has turbine slip ring technology. Although these devices are small, their importance should not be undervalued. Wind turbines require reliable transmission of power and data signals from the nacelle to the control system for…

Slip rings provide a reliable transmission of power or signals from stationary cables in the nacelle to rotating equipment in the hub. A basic slip-ring assembly uses solid metal rings and graphite or precious-metal wire brushes, which contact the outside diameter of the rotating metal ring. As the ring turns, electrical current or signal conducts through…

I’m Nic Sharpley, managing editor of Windpower Engineering & Development magazine. Welcome to another edition of Wind Talk, our podcast series that gives you the opportunity to hear from the industry’s newsmakers in their own words. We have Jesse Shearer, a design engineer with United Equipment Accessories (UEA), a manufacturer of custom components for motion…

A provider of parts and engineering services to wind power industry in North America and a manufacturer of wind turbine and custom components for motion applications worldwide, have announced their partnership in design, manufacture, and distribution of slip rings. UEA slip rings are said offer design versatility as component-kit rings or as completed, ready-to-mount assemblies…

One option that sets UEA slip rings apart from most others manufacturers are its custom wiring harnesses. These harnesses are built in-house to attach to either or both the center leads from the center core stack and/or the brush leads or outer portion of the slip ring assembly. Adding plugs or connectors to the outer…
