The Capella 3 has got a rotor diameter of 109 metres, made of three LM 53.2 blades.
Each blade of a GOLIATH turbine is pitched individually; electric pitch drives and three redundant controllers are located at the hub for easy access and maintenance. All blades are protected with embedded lightning arresters.
Ice detection is based on oscillation. An active cleaning system is used to bring the iced turbine back into operation.
