Abstract :
This paper is focused on measurement and analysis of supply voltage level 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 level and voltage sags in industrial 0.4 kV power systems of Estonia are shown. The impact of shunt capacitors for power factor correction upon supply voltage level is discussed.
