Discuss on Site Application of Generator Partial Discharge On-line Monitoring

Based on application of generator partial-discharge on-line monitoring in Xiaolangdi Hydropower Plant,factors influencing effect of generator partial-discharge on-line monitoring site application are analyzed.According to structure and operation voltage distribution of generator,sensors installing at converging points of stator can locate position of partial-discharge more accurately,which improves effect of monitoring.The results show that sensors installing is the important factor influencing site application effect of generator partial-discharge on-line monitoring system.
