Abstract
Phase-to-phase clearances often are increased in the design of overhead
lines to minimize flashovers caused by galloping of ice-coated conductors
in regions where that occurs. A collection of reports of the observed galloping
behavior of operating lines has been analyzed with the objective of
formulating improved guides for selection of increased clearances. Results
of the analysis show the effects on galloping amplitudes of such line design
parameters as span length and tension.
