Abstract

This paper estimates the quality parameters of electrical energy in the electrical network of the St. Petersburg State Mining Institute. Experimental studies and computer modeling allowed to establish the influence of non-sinusoidal currents of PC power units on the degree of voltage distortion and overestimation of neutral current.
