Effects of internal conductor to enclosure arcs on SF/sub 6/ gas insulated transmission lines

Journal Article · · IEEE Trans. Power Appar. Syst.; (United States)
The effects of internal conductor to enclosure arcs on SF/sub 6/ gas insulated transmission lines (GIL) were tested using 154 kV and 275 kV cables. Tests were conducted on the 154 kV cable with arc currents of 1 KA RMS and 2 KA RMS for durations of 1 about 4 seconds, and on the 275 kV cable with an arc current of 50 KA RMS for durations of 0.1 about 0.4 seconds. Various characteristics of these cables were measured, such as the velocity of arc travel, melting trends of the enclosure wall, the decomposition of SF/sub 6/ gas, the pressure and temperature curves, damage to cable components, and the residual performance capability of damaged components. The data, from these measurements, the findings of these tests, contribute to the improved design and maintenance of GIL systems.
