EPRI AC Transmission Line Reference Book1 - kV and Above EPRI 3rd Ed.The 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.

Two holes are for the insulators 3 and 4and the third hole is for the insulator 7. Each phase contains multiple conductors forming a bundle approximately 16 to 32 inches in diameter. The interphase insulators 7 and 9 will preferably have the same contamination performance as the other insulators used in the V-string. This is a cost effective alternative for use with longer spans in mountainous terrain.Abi-Samra et al. Spacings among the three phases in the example embodiment approximately 14 feet, tertiary requirements relating to dielectric loss and dielectric constant also aboce be observed. In certain situations, 14 feet and 18 feet are maintained using interphase insulators 7 and 9. However, this modification may require increased phase spacings.

This application claims the benefit of U. The present invention is directed to high-capacity, high-efficiency alternating current AC overhead transmission lines. In one embodiment, a power transmission line with a three-phase compact delta configuration is suspended by a single crossarm. The present invention relates to a novel transmission line to maximize load-carrying ability, environmental compatibility, cost effectiveness, and public acceptance. Public interest in clean, reliable power supplies, combined with renewable generation projects being developed in areas remote from load centers, demands transmission infrastructure capable of delivering efficiently large blocks of power over long distances.
