Radial flow water turbine generator is composed of hydraulic turbine and generator using coupling. Hydraulic turbine is mainly composed of volute, impeller, main shaft, seal and suspension et al. As high pressure fluid is guided through inlet pipe into turbine volute, the fluid would force the impeller to rotate. Electricity is generated when the rotor rotates with respect to the stator.

The auto voltage regulator (AVR) is installed within generator to control the output voltage to rated voltage. The induction generator includes brush type induction generator and brushless type induction generator. The brush of brush type generator needs to be replaced periodically. An induction system is installed in induction generator; no exoteric trigger device is required which is easy and user friendly.
