Assessment of 15kV XLPE Industrial Cables based on the Condition Health Index, Prodipto Ghosh, Daniel Goetz, Henning Oetjen PSAMS,  SebaKMT, HDW Electronics

The paper presents the test results of a substantial number of field aged 15kV XLPE cables, which underwent condition assessment testing at a large industrial site. The results of 4 inde- pendent test methods as well as the O&M history of the cables were considered in order to determine their Condition Health Index, CHI, which is correlated to a list of recommended corrective actions. A number of cables were processed according to the recommendations and re-tested. A comparison of the results before and after is provided. The total test sequence comprised a neutral corrosion test, a sheath test, a PD test within the power frequency range and a VLF tan delta test at 0.1Hz. [More]
