Abstract: In order to confirm the fault type and location, this paper anatomized the waveforms and data collected by the fault recording device and carried out inspection according to the analysis results. The inspecting results were consistent to the analysis results. The waveforms and data of the fault recording device were contrasted with the reports and waveforms from the device RCS985GW. The problems existed in protection were discussed and the corresponding suggestions were proposed.
         Key words: stator grounding protection; resonance; data analysis; bus-bar insulator fault
