why we use reduction gear box to reduce turbine high rpm to 1500 rpm in small plant

Answer Posted / k.p.selvakumar.

We design the turbine rpm more than 1500 rpm ,like 5136,or 7700.because,our generator have 1500,rpm .our turbine designed having number of stages.it use for create the torque which we want.
Infact we using 1500 rpm of turbine, it cannot to able to create the desirable torque. So we using reduction gear 1500 rpm.,for high rpm turbine.

DCS marshaling Cabinet Power supply can be replace during plant running time? Answer Yes it is possible. I am talking about the controller and cards power supply modules.
