Abstract in different language: Unequal distribution of excitation current between particular parallel brushes is generally known as well as a sequence of influences which these phenomena implicate. Measurements performed in former times by classical ampere-meters didn’t guarantee instantaneous information about all currents in fixed time as well as about variance of currents in-process of generator. Recent diagnostic and monitoring methods, applied on large generators in Temelín, Dukovany and Bohunice, made possible complex evaluation of current distribution on individual bushes in the course of a long time and statistical calculation of mean value of current on particular polarity, standard deviation and variation coefficient. Following consideration demonstrate one of the way how to qualify current distribution between brushes.
