Answer / lokeshraj

In generator the rotor speed thus frequency varies
according to the flow of water, speed increases with
increase in water flow, turbine torque depends upon the
flow of water....

Answer / milinda

when we increase the flow of water (m3/s) by the governor
(controlling the AREA of the water inlets) we change the
torque on the turbine not the speed,right? but can we change
