Our Wind Turbine Dynamometer series can either load the turbine directly (Turbine Dyno) or load the generator (Generator Dyno). Either system can be used to load the turbine, and measure the mechanical power. The generator dyno can (with optional current clamp meter and voltage probe) also measure the generators output, and thus the generator efficiency (electrical power output divided by mechanical power input). Turbine loading is accomplished by coupling the turbine to an air cooled eddy current dynamometer matching the turbines characteristics. Generator loading is accomplished by applying a controllable electrical load to the generators output. Varying the load allows measurement of the turbines coefficient of performance (Cp) at various Tip-Speed Ratios (TSR). With variations in wind speed this allows complete characterization of the turbine.
