Application of Online PD Monitoring to 400 KV Transmission Underground Cable Systems: Experiences and Outcomes

Inspections, monitoring, analytics, and assessment for the healthiness of High Voltage (HV) power cables are means of ensuring high network reliability. Concerning the electrical characteristics of the insulation system, often a major location for faults, such evaluation can be done through the Partial Discharge Analysis (PDA), a non-intrusive measurement method that can be applied online for the Condition Monitoring (CM) of most electrical apparatuses [1] - [6] .
