- , - I. V. Hlad1 A. O. Solomchak1 Research of nonlinearity of electrical group loads settlements Ivano-Frankivsk National Technical University of Oil and Gas The results of experimental research of the group load transformer substations of settlements have been offered. The spectral composition of the phase currents and voltages has been carried on, non-sinusoidal currents to 40 % have been detected and the character of their changes during the day has been determined in the paper.

Keywords: non-sinusoidal, current, voltage, load, higher harmonics.
