Methods and technical means of reducing power losses in 0.38 kV networks with a symmetering device

Abstract

The relevance of this paper is due to the need to solve a specific problem, which is the reduction of power losses in asymmetrical electric receivers. The purpose of this paper is to develop methodological prerequisites for analyzing ways to reduce power losses caused by asymmetry of currents in a 0.38 kV network and to study the influence of current asymmetry on the increase of electrical losses, as well as to determine the effectiveness of symmetrical devices in reducing these losses. Among the methods used, we should mention the analytical method, classification method, functional method, statistical method, synthesis method and others. This paper highlights the issue of developing a methodology and theoretical studies, as well as conducting experimental studies on additional power losses caused by asymmetry of currents and voltages in 0.38 kV networks using symmetrical devices. The solution of problems of power supply and improvement of electric power quality in such low-voltage networks is closely connected with the problem of current asymmetry reduction. This study is of practical importance as it contributes new scientific knowledge and offers practical recommendations for effective improvement of low-voltage power networks.
