To the extent that my work will explore specific applications of induction generators, I will be examining their use in harnessing wind power: specifically the unique restrictions that turbines and other types of casings impose. For busbars it is constant, but for the inductor part, we have to take into account its impedance which is changing in time due to the change of magnetic permeability \mu of the workpiece. Thus, the machine is now working as an induction generator (asynchronous generator). Generally any generator larger than about 20 kW will be above 90% efficient. The voltage drop ratio on all three parts are the same as for the resistance V1:V2:VcoilV_1 : V_2 : V_{coil}V1:V2:Vcoil. Or Output can be written as Input - loss .
