Recommendations for geodesy of operation of turbogenerator and its foundations

General requirements are listed for geodetic measurements in determining deformation of the turbogenerator-foundation system. The measurements are described of deformation of the top part of the foundation following the assembly of the turbogenerator and in the turbogenerator operating mode ''on-off-on''. Deformations are also measured of turbogenerators separately in the period between repairs and during the mode ''on-off-on''. For each type of measurement, the order and the number of measuring cycles are tabulated, the method of measurement and of plotting the deformation graphs are described. (E.J.). 4 tabs
