| Abstract: | The on line monitoring of partial discharge is an effective approach for diagnosing the faults of stator winding insulations in HV rotating electrical machines.Several methods of on line monitoring of partial discharge for HV electrical machines are introduced in the paper.The PD monitors are based on:(1)a pair of capacitive coupler;(2)a RF current transformer;(3)a pair of bus coupler;(4)the stator slot coupler(SSC);(5)the wires of a resistance temperature detector.And the arrangements of couplers or sensors,the noise rejection techniques and their applications are introduced mainly. |
