Abstract: A tether may include a core, a plurality of electrical conductors wound around the core, and a jacket surrounding the plurality of electrical conductors. The plurality of electrical conductors may include at least two groups of electrical conductors. Each group of electrical conductors of the at least two groups of electrical conductors may define a respective electrical path, where the respective electrical path is different from the electrical paths defined by other groups of electrical conductors of the at least two groups of the electrical conductors. Moreover, each group of electrical conductors of the at least two groups of electrical conductors is located around a respective portion of the core, such that a cross-section of each group of electrical conductors of the at least two or more electrical conductors defines a respective arc around the respective portion of the core.

Abstract: A method may involve transmitting power between a tethered aerial vehicle equipped with wind turbines for generating power and a ground station configured to interconnect the generated power to an electrical distribution network. The power may be transmitted using high voltage, high frequency AC electrical signals, and transformers at the ground station and the aerial vehicle can scale the AC voltage for use at the respective locations. Converters at the ground station and the aerial vehicle can then convert the transformed voltage to DC. The AC voltage may be transmitted through the tether at a resonant frequency of the tether based in part on an internal capacitance between multiple conductive paths on the tether.
