News & Events « Powerline Patrol ServicesThe technique used in this paper is based on optimal conductor arrangements obtained using the Genetic Algorithm. The input data to the genetic algorithm include the clearances between conductors and earthed objects, the clearances between individual conductors, and the calculated values of electric and magnetic fields EMFs and the radio interference RI. On the other hand, the excitation function method is used to calculate the RI. The comparison between the results of both conventional and optimal arrangements indicates the effective of the optimal one. This is a preview of subscription content, log in to check access.

The six V-string insulator assemblies preferably include eight phase-to-ground insulators and four interphase insulators. The V-string insulator assemblies can be substituted with braced-post-insulator and I-string suspension-insulator assemblies to keep the phases in a similar delta configuration with no interphase insulators.

The structure according to claim 1, wherein the second conductor bundle is connected to the crossarm epgi no other conductor bundle disposed therebetween. I have studied why min. Pfitzer et al. Yoke plate 5 can be replaced by yoke plate 53 for three-conductor phase bundles FIG.
The structure according to claim 6, wherein the second conductor bundle of the first three-phase circuit is connected to the crossarm with no other conductor bundle disposed therebetween. Ground-level electric fields produced by the present invention and typical designs are very weak, although electric fields associated with the former are higher. Integrating a kV or a kV line with kV transmission would require transformers and other station equipment, the cost of which is not included in this comparison.

For a given line length, with the kV design of the present invention being significantly more cost effective due to its higher loadability-an important objective in bulk power transmission development, is to raise linee transmission voltage class. Fernandes et al. Caola et al. Energy efficiencies and installed costs of the two designs are similar.
