| Abstract: | Three typical kinds of discharges in hydro generator stator windings were studied in the paper.In the experiment,the simulated discharge pulses with a rise time of several ns to nearly one hundred ns are injected into the single generator bars and the whole stator winding of a 36 MW/10.5 kV hydro generator,the responses are reported respectively.This article also introduces the application of virtual instrument technology,which takes place on the On-line VHF Detecting System for Hydro generator. |
