Abstract

Abstract: The main technical parameters and stator winding of generator No.2 of Zilanba Hydropower Station were introduced. The reasons of stator Bphase grounding fault were analyzed. The method for locating the fault points, the resolving process and resolving method of the fault were discussed. Combining with field practical situation, four measures for generator stator maintenance were proposed.

Key words: generator, stator B-phase grounding fault, analysis, inspection method, inspection process, precautionary measure
