摘要：
The feasibility of on-line Partial Discharge (PD) monitoring for condition monitoring of medium voltage (MV) cable systems was studied. A total of 19 MV feeders with two different cable types and various ages have now been succesfully monitored for 2-18 months in Helsinki. These PD measurement sensors can be installed without any switching activities and thus interruptions. On-line monitoring indicated similar results with off-line PD measurements. It is stated that on-line monitoring can give reliable condition information of MV cable assets in real time.
