Corona loss measurements for the design of transmission lines to operate between 220 kv. and 330 kv.

摘要

DURING the summer and fall of 1931, measurements at the Harris J. Ryan Laboratory, Stanford University, Calif., extended the range of corona loss data for conductor sizes beyond those investigated during 1930. In these latter tests the 3 conductor specimens studied were a 1.125-in. hollow copper cable, a 1.49-in. hollow copper cable, and a 2.0-in. hollow aluminum cable. The losses were measured on a 3-phase line 700 ft. long. Voltages as high as 600 kv. between lines were used.
