Guide vanes are used as governor in Kaplan turbine. Correct Answer True

Guide vanes are used as governor in Francis and Kaplan turbines. These guide vanes controls the flow of water to the turbine and hence governs the speed of rotation of turbine. Under different loading conditions the speed of rotation of turbine is needed to be controlled for constant frequency output.
