Abstract

The degree of voltage unbalance in electric power network is subject to limitation, and its value is defined by the regulations. Unbalance of output voltage of power transformers is caused mainly by asymmetric loads. The paper presents analysis of the effect of various types of load asymmetry on the value of the factor. The analysis was carried out with the help of the Mathcad software.
