| Abstract: | The causes and damages of partial discharge in HV electrical machines are analyzed. Several methods of on line monitoring of partial discharge for HV electrical machines such as high frequency current coupler monitoring,Rokowski winding monitoring,radio frequency monitoring,radio discharge analyzer monitoring,a pair of bus coupler monitoring,the stator slot coupler monitoring and the wires of a resistance temperature detector monitoring are introduced. These methods help to improve the maintenance of HV electrical machine. |
