Partial Discharge Detection Technology in Power Cable Faults Research and Application in Online Monitoring
Partial discharge detection is an important means to evaluate the insulation condition of cross-linked polyethylene power cables.In this paper,a partial discharge online monitoring system for medium voltage XLPE cables is developed,and its working principle,hardware composition,software design and implementation scheme are elaborated in detail.The system comprehensively evaluates the insulation condition of XLPE cables by monitoring the partial discharge signal in the ground wire of XLPE cables.The field operation results show that the system is stable and reliable.
