Developing a Method Providing for the Accurate Assessment of Actual 6(10) kV Transformer Load Using Data from Smart Electric Energy Metering Systems

The article presents the development of a method providing for the accurate assessment of actual 6(10) kV transformer load using data from smart electric energy metering systems. Th equipment load is currently assessed by defining the subscribed consumer power and as of the measuring day results. This leads to a significantly higher equipment load coefficient and, consequently, to an incorrect technical decision to install or replace a transformer for a higher power equipment. In its turn, this causes increased electric energy losses and lower electric energy transmission and distribution efficiency. The developed method allows for the accurate assessment of the actual transformer load coefficient, followed by a correct technical decision to replace or install a higher power equipment. The latter results in the increased load for the low-loaded equipment, lower technical losses and improved efficiency of electric energy transmission and distribution.
