In order to establish if a transformer corresponds to the requirements of the power network, it is mandatory to know the consumption characteristics. Heretofore, the determination of load level of transformers was performed based on technical-economic criteria. However, for the situation in which the real load would be equal to the one resulting from calculations, this fact would be valid only for a short time period, maximum two years, but the calculation based on the total updated expenditure is performed for a twenty years period, in which it is more than certain that the load will undergo variations within certain limits compared to the initial one. The central theme of this paper is represented by the development of an optimal quality management algorithm for assessing the load of transformers, which provides more information related to the economic usage capacity level, the value of power losses, economic transient power, possible over-voltages, the pricing of energy and charging of energy losses. In the end, results have been simulated for three series of mining transformers with different transformation ratios.

W celu ustalenia, czy transformator odpowiada wymaganiom sieci energetycznej, obowiązkowe jest poznanie charakterystyki zużycia. Dotychczas wyznaczanie poziomu obciążenia transformatorów odbywało się w oparciu o kryteria techniczno-ekonomiczne. Jednakże w sytuacji, w której rzeczywiste obciążenie byłoby równe wynikowi wynikającemu z obliczeń, fakt ten byłby ważny tylko przez krótki okres, maksymalnie dwa lata, ale obliczenia oparte na całkowitych zaktualizowanych wydatkach są dokonywane dla dwudziestu, w okresie, w którym jest więcej niż pewne, że obciążenie ulegnie zmianom w pewnych granicach w porównaniu z okresem początkowym. Głównym tematem tego artykułu jest opracowanie optymalnego algorytmu zarządzania jakością do oceny obciążenia transformatorów, który dostarcza więcej informacji dotyczących ekonomicznego poziomu wykorzystania mocy, wartości strat mocy, ekonomicznej przejściowej mocy, możliwych przepięć, wycena energii i pobieranie strat energii. W efekcie symulowano wyniki dla trzech serii transformatorów górniczych o różnych współczynnikach transformacji.
