This paper presents considerations related to tlie loss of life calculation and to the determination of tlie distribution transformers loading, with technical and economical consideratioiis and applying daily load curves obtained from measurements in typical transformers. Loss of life estimation is done applying probabilistic daily load curves and their probability of occurrence. The transformer loading rnanagement criteria is then compared to tlie methodology presently in use by Silo Paulo State utilities. Finally a transformer loading analysis is done through an economic criteria that consists on the calculation of tlie investment cost, losses, and the loss of life cost, all during its operational life.
