The research objective is to analyse the quality of the electrical energy in transformer chamber II of the Technical University of Cotopaxi. The study combines real-time measurements and a subsequent analysis of historical data collected through monitoring instruments on the main panel. The data obtained shows patterns of disturbances caused mainly by non-linear loads. The analysis of the odd current harmonics reveals a clear predominance of the third harmonic in the three phases L1, L2 and L3, a common characteristic in three-phase systems with non-linear loads. The amplitudes of this harmonic are especially significant in L2 and L3. The context of the generator ignition reinforces the hypothesis that said equipment, or the loads it feeds, constitute a source of harmonic distortion; these data are relevant for the current evaluation.
