The name Deriaz comes from its inventor Paul Deriaz. It is a Kaplan turbine including blades which makes the turbine more suitable for higher heads. The Deriaz turbine efficiently works at a range between 20 meters and 10 meters. Deraiz turbine has several advantages over another turbine as it has both fixed and adjustable blades. Servometer and operating mechanism help in adjusting the running blade according to load. This turbine can be used for various loads. In comparison with the Kaplan turbine, it has more efficiency and has higher cavitation coefficient. Last but not least, these turbines can even work for a reversible pump-turbine service.
