The maximum power output of a wind turbine is 20kW. It has a single phase, 240 volts AC generator. Remember that 240 volts is the RMS value. What is the PEAK current produced at the 20 kW?

Solution

given P=20KW

V_rms=240v

we have P=VI where V and I are rms values

         20*10^3=240*I

I=(20*10^3)/240

I=83.33A it is the rms value of current

now to find peak value of current we have

I_m=sqrt2*V_rms

    =1.414*83.33

    =117.85A is the peak value of current
