Resumen
This work aims to predict the total maximum demand of a transformer that will be
used in power systems to attend a Multiple Unit Consumption (MUC) in design. In 1987,
COSERN noted that calculation of maximum total demand for a building should be different
from that which defines the scaling of the input protection extension in order to not
overestimate the power of the transformer. Since then there have been many changes, both in
consumption habits of the population, as in electrical appliances, so that this work will
endeavor to improve the estimation of peak demand. For the survey, data were collected for
identification and electrical projects in different MUCs located in Natal. In some of them,
measurements were made of demand for 7 consecutive days and adjusted for an integration
interval of 30 minutes. The estimation of the maximum demand was made through
mathematical models that calculate the desired response from a set of information previously
known of MUCs. The models tested were simple linear regressions, multiple linear
regressions and artificial neural networks. The various calculated results over the study were
compared, and ultimately, the best answer found was put into comparison with the previously
proposed model
