Symmetrical Components

Symmetrical Components is a mathematical technique for analyzing unbalanced three-phase electrical circuits by decomposing them into balanced component sets. Introduced by Charles Fortescue in 1918, the method transforms the complex analysis of unbalanced systems into simpler balanced equivalent circuits. Symmetrical components are fundamental to understanding faults, protection coordination, and stability in power systems, remaining essential in modern grid operations.
