Abstract
Tan δ (dissipation factor)data on Cable System B is updated to include the full 2-year 500/550 kV test program at Waltz Mill and the 10-month 765/800 kV extended test program. This data is analyzed, demonstrating no change with time of tan δ for the system. Particular attention is paid to the paper splice, which exhibits a thermoelectric stability limitation at the 765/800 kV level. The outstanding performance of the PP/C splice is emphasized. Consideration of the operation of a very highly stressed oil impregnated paper insulation HPOF pipe system at 765 kV is suggested, including potential single circuit transmission capacity calculations.Keywords
