The influence of line configuration on environment impacts of electrical origin for 800 and 1100 kV overhead lines.
Investigate the effect that varying line parameters has on the electrically generated environmental impacts of 800 and 1100 kV overhead lines.
The aim of this new work is to show how different design parameters of 800 and 1100 kV overhead lines affect on electrical impacts and the way to reduce these impacts by using appropriate parameters. The design parameters considered are the phase configuration, the number and diameter of sub-conductors per phase, the sub-conductor spacing, the phase to phase distance and the clearance to ground. The impacts include electric and magnetic fields, radio interference and audible noise.
