WHITEPAPER: Online Partial Discharge Detection and Location of the Underground Cables by Using Different Approach

This paper presents the current technology used to identify the partial discharge of underground cables without taking a shutdown, how could be able to do measurement and prevent catastrophic failures of the cable joints and terminations. Such online measurement enable us to assess condition of the insulation of the power cables and can be used as a tool to endure the reliability of the plant. The use of online measurement to identify and confirm the PD activity with various sensors. How expert analysis software can help to PD and Noise as a different classification shown in this paper with real case study, where PD detected at termination of the cable on site using combination of different sensors.
