Abstract
It is proposed that the mechanical state of turbogenerators be regularly monitored by photoelectric chronometric recording of low-frequency torsional vibrations of their shafts. The vibrations are caused by small sudden changes which are continuously occurring in the operating parameters of the turbine unit.
