For the first time, we have established a mathematical relationship between spatial representation of instantaneous values of the vector components and the total losses power in the three-phase four-wire energy supply systems. <strong>Practical value.</strong> We have elucidated an issue that using the proposed methodology would create a measuring device for determining the current value of the components of total losses power in three-phase systems. The device operates with measuring information about instantaneous values of currents and voltages. </em>}, number={2}, journal={Electrical Engineering & Electromechanics}, author={Zhemerov, George G. and Tugay, D.
