Abstract

This article contains a detailed study of the parameters and electric characteristics of a transmission system proposed to electrically connect the cities of Tucuruí, Macapá and Manaus. Several sections of this transmission line will be supported by steel towers 280 m high to suspend the line above the Amazon tropical forest. The height of the line and the presence of two dielectrics in the system—the air and the forest—produce unique line parameters compared to the longitudinal parameters of a conventional line, which is approximately 40 m high. A preliminary analysis of the parameters of a line section of the Tucuruí–Macapá–Manaus connection is conducted in this article. The behaviors of potential surges in the line resulting from switching operations and atmospheric discharges are also investigated.
