Research on the shaft insulation monitoring plan for Three Gorges Power Plant water-turbine generator set and its engineering application

Concrete arrangement of the four bearings of the Three Gorges Power Plant water-turbine generator set and the reason producing shaft current and its harm are introduced.By combining the actual measurement data,the axis CT survey way flaw is showed.A comprehensive solution to concrete implementation of the proposed new plan and the existing problems in the engineering application are presented.
