Delta-Wye (Δ-Y) Transformation
Three resistors connected in a delta (Δ) configuration can be replaced by an electrically equivalent wye (Y) configuration, useful for simplifying circuit analysis. The conversion formulas are Ra = (Rab × Rca)/(Rab+Rbc+Rca), Rb = (Rab × Rbc)/(Rab+Rbc+Rca), and Rc = (Rbc × Rca)/(Rab+Rbc+Rca).
Each wye resistor sits at one of the three delta’s corners, connecting to the two delta resistors that meet at that corner. This transformation preserves the network’s behavior as seen from its three external terminals and is a standard technique in three-phase power system analysis and general circuit simplification.
