The computation of accidental energizing of an off-line turbogenerator has been conducted. Inadvertent energizing of a turbogenerator has become a particular issue in a power plant. The investigated case is three phase energizing. Great emphasis is placed on physical phenomena occurring in the rotor. The results of computations allow one to indicate the risks of damages of construction elements and can confirm the limits of the values set in dedicated protection devices.
