| Abstract: | In order to improve the identification ability of current generator supervision system on the grounding fault of generator rotor, a new protection theory is researched and a corresponding digital protection device is developed. The device can be used to real-time monitor the insulation of generator rotor's windings, identify rotor's grounding fault and determine fault location, and the new protection device is of high sensitivity. The system has been put into operation with better effects. |
