Abstract
ONE LIMITATION of previously known methods of melting ice from transmission lines has been the range of line lengths that could be so treated while in service. The 60° phase-shift method is applicable to 34.5 kv lines of only 25 to 35 miles in length depending upon design impedance and conductor size. To circumvent this limitation, methods of shifting phases 19° and 41° were developed. The range of lengths that can now be cleared of ice while in service has been increased to include lines 5 to 25 miles long.
