Three-phase power systems are the backbone of modern electrical engineering and industrial power applications. This course is designed to help you fully understand three-phase systems from fundamentals to advanced analysis, using a powerful combination of theory, numerical problem-solving, and MATLAB/SIMULINK simulations.

You will begin by learning why three-phase systems outperform single-phase systems, exploring key advantages such as higher efficiency, smoother power delivery, and reduced losses. The course then explains how three-phase systems are generated, followed by a structured introduction to three-phase circuits, including Star (Y) and Delta (Δ) configurations.

Step-by-step lessons guide you through balanced three-phase Star and Delta load analysis, supported by solved numerical examples and detailed MATLAB/SIMULINK models. You will learn how to calculate line and phase voltages, currents, and power, and then verify your results through simulation. Dedicated sections focus on three-phase power concepts, including real, reactive, and apparent power, along with a complete solved example using both manual calculations and SIMULINK.

The course also covers power factor correction in three-phase systems, explaining its importance in improving system efficiency and reducing energy costs. Advanced modules address unbalanced three-phase systems, including unbalanced Star and Delta loads, systems with and without neutral wires, and the impact of neutral wire impedance.

Finally, you will learn how to analyse unbalanced three-phase systems using symmetrical components, a critical technique used in power system analysis and fault studies.

This course is ideal for electrical engineering students, diploma holders, and practising engineers who want practical, simulation-based mastery of three-phase power systems.
