Star (Wye) and Delta-Connected Loads | What Is 3-Phase Power? -- Part 2

In 3-phase electrical power systems, there are two fundamental connection options for load components: Star (Wye)-Connected Loads and Delta-Connected Loads. Understanding how these connection options affect voltage and current is fundamentally important for AC electrical system analysis and operation.

You will learn:

- How Star (Wye) and Delta Connection are made in a 3-phase system

- The definition of line measurements and phase measurements for both voltage and current

- The vector relationship between line and phase measurements for both Star- and Delta-Connected Loads

- Some practical considerations for a certain connection choice
