Composite structural elements of overhead lines as a means of increasing technical efficiency

Abstract

Abstract Innovations in engineering and technologies depend not so much on emergence of new properties of the equipment, production process, system of management of the enterprise, but to a greater extent on their occurrence in the necessary set of combination. Technical and economic indicators reflecting technical and economic efficiency are usually used as characteristics. The degree of technical efficiency is determined by a combination of three properties – safety, reliability and productivity. These basic properties determine the economic effect of an innovative product performing certain functions, enabling to estimate their usefulness and significance. One of the means of increasing the overhead lines technical efficiency in the electric grid is the introduction of composite structural elements. The overhead line model is proposed for assessing the impact of elements on reliability as a component of technical efficiency. Changes in the reliability of the line when introducing innovative elements are calculated and priorities are defined.
