EE 205 Dr. Chokri. Belhaj Ahmed - 2 - Objective of this lecture is as follows : ± Transformation from Delta to Why. ± Transformation from Why to Delta. ± The single-phase equivalent circuit. ± The line and phase current quantities for a Delta circuit. ± Complete Analysis of Y- circuit. After finishing this lecture, you should be able to : ± Transform the three-phase circuit Y to and vice versa. ± Extract the single-phase equivalent circuit for Y- three-phase circuit. ± Deduce the line and phase current quantities for connection. ± Identify the difference between delta and why currents and voltage relations. ± Conduct a complete analysis for Y- circuit.
