Recommendations are made to operating utility companies not to do dc acceptance proof or maintenance testing at 40 kV on XLPE insulated cables, failed once in service and then spliced. DC testing can be done at 55 kV in the field on a new cable prior to energizing when there is no aged cable spliced in the system. Similar records in OSTI. GOV collections:.

Full Record Other Related Research. Abstract This project was initiated to investigate the effect of dc testing on extruded crosslinked polyethylene XLPE insulated cables. Effect of dc testing on extruded cross-linked polyethylene insulated cables. United States: N. Copy to clipboard. United States. Statistical analysis of the data revealed a probable existence of an inflection point in the aging time, beyond which cables subjected to multiple dc voltage applications during aging start to fail at an increased rate.

Most work was performed with spliced cables, as described in the Phase 1 report. Results confirm earlier findings that dc testing has a deleterious effect on an aged crosslinked polyethylene insulated cable. However, the cable subjected to dc testing fails earlier upon further ac aging. Recommendations have been made to operating utility companies not to perform dc testing on a crosslinked polyethylene insulated cables after they have more » been energized in service. Similar records in OSTI. GOV collections:.
Phase 2, Final report. Title: Effect of dc testing on extruded crosslinked polyethylene insulated cables. Full Record Other Related Research. Abstract In order to investigate the effect of dc testing on crosslinked polyethylene insulated cables, a research project was initiated under the auspices of Electric Power Research Institute.
