A sudden shut-down accident of the C-phase GIL tubular busbar in a hydropower station during its normal op-eration was encountered due to a discharge fault of the conductor to the case.Possible reasons of this fault are analyzed with the monitoring data before the accident and the breakdown products of the insulation gas after the accident.Im-provement measures are suggested for the monitoring of the tubular busbar.After the replacement of the faulty busbar, the accident is solved.
