In this paper, a practical laboratory exercise performed at the Laboratory for Electrical Engineering in the Higher Education Technical School of Professional Studies in Novi Sad, as an integral part of the subject Practicum is presented. The aim of the exercise is to introduce students to the phenomena of transfer of complex power along the distribution line, voltage drop, power losses, types of consumption, but also the methodology for the measurement and calculation of basic electrical quantities on the distribution line. The test network is a single-phase model of the three-phase low-voltage cable line. As a part of the exercise, measurements of voltage, current, active and reactive power and power factor are performed. The exercise analyzes the impact of X/R of the line and the type of consumption (resistive, resistive-inductive, resistive-capacitive, and motor) on the basic power system quantities.
