Kaplan Turbine is widely used in power production worldwide. It covers hydroelectric power stations with extremely low head heights. In particular, the Cabran type is particularly suitable for hydroelectric power plants installed in high-flow water conditions under the above conditions. The cheap microturbines built on the prototype of kaplan turbine are specially designed for individual power generation sites. These microturbines can be designed for head heights of at least 0.3 meters. They are not focused on whether they are highly efficient or not. It needs to be able to run with sufficient water.
