Answer / dr.atul bansod
Elevation is given for compensation of natural sag of heavy rotors.Steam turbine manufacturer submits a document known as deflection curve for rotors. On that curve '0'point is specified (any bearing) and other bearings ar kept on different elevation with reference to this "0" refereed bearing.
