The electrical generators used for wind turbines on sites where there is an access to the seasonal monsoon winds, produce an output AC of 240 V and a frequency of 50 Hz even when the wind speed is fluctuating.
A transformer may be required to increase or decrease the voltage so it is compatible with the end usage, distribution or transmission voltage, depending on the type of interconnection.
