Using the theory of electrical engineering for the load sinusoidal voltage and current, the power losses in the transmission line represented by an L-type equivalent circuit are determined. It is found out that for a cable transmission line the total power loss depends on both the real values of voltage and current and the difference between the initial phases of the latter. This results in a change in power losses in the line under conditions of constant real values of voltage and current – apparent power.

PL

Określono analitycznie straty mocy w linii przesyłowej, reprezentowane przez równoważny obwód typu L. Ustalono, że dla linii transmisji kablowej całkowita strata mocy zależy zarówno od skutecznych wartości napięcia i prądu, jak i od różnicy między początkowymi fazami tej ostatniej. Prowadzi to straty mocy w warunkach stałych wartości prądu i napięcia.
