Slip rings allow power and signal to be passed through rotating parts. In wind turbines slip rings are used to supply power and signal to the pitch system through the main shaft. They are also used to carry power off the generator from the 1500 rpm rotating part to the bus bars and then down-tower for power conditioning. A critical component for wind turbines as failure results in loss of communication to the turbine in the event of pitch slip ring failure. Or the event of generator slip ring failure this can result in thermal events (fires). Quality manufacture of slip rings and proper maintenance practices are key to good operating practices.
