Symmetrical Components | What Is 3-Phase Power? -- Part 4

 In 3-phase electrical power systems, system operation can either be balanced or unbalanced. Unbalanced operation is undesirable, and there needs to be a good way to analyze system imbalance so you can assess the severity of an imbalance, define appropriate settings for protection relays, and drive appropriate control mechanisms to address an imbalance. Learn how to effectively analyze system imbalance through symmetrical components.

You will learn:
- How a 3-phase voltage/current is decomposed into positive-sequence, negative-sequence, and zero-sequence symmetrical components
- The circumstances under which negative-sequence and zero-sequence components will show up in a system response
- How system faults can be described by symmetrical components
- How to compensate for a system imbalance using negative-sequence current injection
