This article begins with a study of transformer additional losses due to the presence of non-sinusoidal loads, presents existing models to represent these losses and proposes an original model. Consequent increment in transformer loss of life is Studied by means of a sensitivity analysis of the model to transformer rated power, load amplitude, thermal inertia, profiles correlation and harmonic spectrum content.
