| Abstract: | The search method and the analysis of causes of rotor windings unstable high resistance multi - point ground fault of a 350 MW turbo - generator in a power plant was describd. To ensure the repairment quality, in addition to regular tests conducted as required by pre - voltages of two poles of rotor windings is proposed on trial procedures,the way of measuring the impedance the basis of the actual situation. |
