Abstract: The present invention corresponds to a method and an apparatus for detecting faults in transmission and distribution systems.

Abstract: The invention is related to a rotor blade for the generation of electrical power. The rotor blade transforms the kinetic energy of a fluid, into rotational movement of a mechanical shaft. The shape of the rotor blade is characterized in that, along an axis, it is longitudinally bound by a root (a) and a tip (b), which are connected through multiples curved segments, called neutral sectional axes [Eni]. All [Eni] generate a continuous or discontinuous curvature called Primary Neutral Axis [En]. The point corresponding to a leading edge and a trailing edge, configure an airfoil [PAij]. The curvature of the blade (e) has an arch of length L, and is defined by the neutral sectional axes [Eni]. The blade (e) is defined by at least one continuous curved section called primary neutral axis [En] having a length [Ln]. The blade's shape has a variable cross section along the Primary Neutral Axis [En].

Abstract: The invention relates to a system for generating electrical energy from wind energy, said system being characterized in that the design makes use of small air currents and does not require a large amount of air in order to generate electrical energy or power. This system incorporates two generating technologies designed based on the vertical rotation axis concept, achieving movement that is independent of wind direction. The invention combines two technologies, namely: one based on drag forces, ideal for low speed conditions; and another based on lift force, which is best for high speed work.
