Abstract
ENG: The paper presents a theoretical background to determine the inactive power consumption features, i.e.
the reactive power according to S. Fryze approach of the electric transport systems. Traction electric circuits of
transport facilities of electric locomotives, feeder traction substations and city trams used in Ukraine demonstrate
three features of the reactive power. According to the classical method, the inequality between the active and total
power indicates the presence of the reactive power. The second feature is the time variation of an instantaneous
impedance or instantaneous conductivity. The third is the inequality between the instantaneous reactive power to
zero and the nature of its sign throughout the time of the electric power system consumption. The reactive power
consumption gives rise to considerable additional power losses in the electric traction transport systems.
