Описание: Balanced Three-Phase Circuits: Analysis and Applications in Power Systems

A balanced three-phase circuit is an electrical system where the three AC voltage sources have equal magnitudes and are phase-shifted by 120 degrees from each other. Crucially, the connected load also exhibits identical impedance in all three phases. This symmetry leads to significant advantages, including constant instantaneous power delivery, zero current in the neutral wire (in a wye-connected system), and efficient power transmission. It's the most common configuration for industrial and commercial power distribution due to its efficiency and smooth operation of motors and other three-phase equipment.
