Abstract: The paper presents some typical daily load curves formed by averaging data collected by the system for remote energy meter reading in time period longer than two years. Data from nearly 7000 energy meters at low-voltage consumers are processed, statistically reliable daily load curves are obtained and their characteristics are listed. Typical load duration curves of months belonging to winter and summer season are formed on the basis of daily load curves and depicted in the paper. These seasonal load duration curves of different load classes at low voltage are mutually compared. The influence of different number of working days, Saturdays and Sundays on monthly load duration curves is discussed, and corresponding load factors and loss factors for winter and summer months are statistically analysed.

Keywords: seasonal load curves; remote energy meters; load duration curves; low voltage consumers; load factors; loss factors.
