Abstract :
The paper presents the results of several months monitoring of voltage events in a low-voltage distribution network. Voltage dips, short interruptions and overvoltages in voltage supply are considered in the study. The voltage event detection method employed uses three Kalman Filters, one per voltage phase, to detect and estimate in real-time the magnitude and phase angle of the three-phase voltage supply during the event. Statistical analysis of the voltage events recorded and the effect of these voltage events on equipment are also considered in the paper.
