Line constant measurements and loading current test in long-distance 275 kV GIL.

Line constant measurements and loading current test in long-distance 275 kV GIL.

This paper reports on the results of a loading current test and measurements of the line constants of a long-distance gas-insulated transmission line (GIL) in a tunnel. The loading current test was carried out at 80% rated current, to verify the soundness of the thermal expansion and contraction of...
