The traditional operating mechanism of Kaplan turbine blades involves an external power supply transmitted to the runner hub by oil pressure. In the Carillon turbines the only connections to the hub are a flexible electric cable and a mechanical valve-operating rod. Elimination of the oil supply lines has been achieved by reducing the power requirement for moving the blades, by use of roller bearings and slow blade operation, and by providing suitable means of energy conversion within the hub. The paper describes the mechanism used and gives first field data on blade torques.
