| Abstract: | On-line monitoring of partial discharge(PD)in turbine generator is an important test for assessing the condition of generator insulation system.In this paper, a broadband current transducer for on-line monitoring of PD in turbine generator has been studied. The transducer has been used to detect three types of simulated origins of PD which often exist in turbine generator stator winding(discharges in cavity, discharges at end winding and discharges due to broken strand). Some on-line monitoring results of PD in turbine generator with the transducer are presented. |
