Abstract

The electrical power distribution systems (EPDS) possess a great dynamics of development. Thanks to this phenomenon in the electrical power distribution systems (EPDS) the probability of asymmetrical regimes apparatus increases monotonously. As a result of this reliability the functioning of the electrical power equipment installed in the electrical knots changes. The asymmetrical regimes in the electrical power distribution systems accompanied by the short circuit current represent a function of a determinate row and it is a vague factor of probabilistic nature. As a result it can be argued that the investigation of the influence of the asymmetrical regimes accompanied by short circuit current on the reliability of the Electrical Power Distribution Systems is one of the most important problems of the EPDS development. The short circuit currents influence the structural and functional reliability of distribution networks and the reliability of electrical equipment installation
