In the last post (Symmetrical Components Made Easy – Part 1), we examined and calculated the symmetrical components in a non-faulted three-phase electrical power system. This post expands on the same analysis of using phasor to describe, understand, visualize and calculate the three symmetrical components: Positive, Negative and Zero Sequence components. An examination of a […]

Before computer software applications, the task of calculating fault currents for a three-phase electrical system was a challenging task. A mathematical theorem using Symmetrical Components and Sequence Networks was the most practical method to conduct fault studies. Although we now have computers systems to calculate and perform in-depth fault and coordination studies, there continues to […]
