This paper is focused on the measurement and analysis of supply voltage quality in low voltage industrial power systems in Estonia. A practical method for analysis of supply voltage quality parameters, implementing stochastic theory, is discussed. Measurement results of supply voltage quality parameters – voltage magnitude, voltage events, harmonics, flicker and unbalance in industrial 0.4 kV power systems of Estonia – are shown.
