Field Test of 15-kV Cable Terminations

This is a progress report by Houston Lighting & Power Company (HL&PCO) on testing 15-kV cable terminations in a marine environment. The test rack, which has been intermittently energized since December 10, 1965, supports 70 terminations on test including those with porcelain, tape, and other materials for an exterior surface. All failures are believed caused by leakage current. Eighty-one percent of the porcelain terminations that were on test are still operating. All of the taped outdoor terminations on test are considered failed. Some of the other terminations, the nonporcelain and nontaped terminations, are still operating and look very encouraging and promising.
