Abstract :
The recorded phase-to-phase faults associated with the full-span galloping of CEGB overhead transmission lines over a 7-year period have been correlated in the form of histograms of number of faults as a function of wind speeds prevailing at the times of the faults. It is shown that, for bundled conductors, the results are in reasonable agreement with the theoretical predictions of Hunt and Richards for the minimum wind speeds necessary to cause phase-to-phase faults.
