Given star resistances Ra, Rb, Rc, the equivalent delta resistances are: R12 = (Ra + Rb + (Ra Rb)/Rc) — commonly re-expressed as: R12 = (Ra Rb + Rb Rc + Rc Ra) / Rc R23 = (Rb Rc + Rc Ra + Ra Rb) / Ra R31 = (Rc Ra + Ra Rb + Rb Rc) / Rb star delta transformation problems and solutions pdf

∑R=RXY+RYZ+RZX=10+20+30=60Ωsum of cap R equals cap R sub cap X cap Y end-sub plus cap R sub cap Y cap Z end-sub plus cap R sub cap Z cap X end-sub equals 10 plus 20 plus 30 equals 60 space cap omega

Convert the delta formed by the two arms from A and the middle resistor.

If all three resistors in the star are equal ((R_Y)), then each resistor in the delta is (R_\Delta = 3R_Y). R1=10⋅3060=30060=5Ωcap R sub 1 equals the fraction with

Example 2 — Y → Δ: Combine to remove central node Problem: Star resistances Ra = 5 Ω, Rb = 10 Ω, Rc = 15 Ω. Find equivalent delta resistor between nodes 1–2. Solution: S = Ra Rb + Rb Rc + Rc Ra = 5 10 + 10 15 + 15 5 = 50 + 150 + 75 = 275 Ω R12 = S / Rc = 275 / 15 ≈ 18.333 Ω R23 = 275 / Ra = 275 / 5 = 55 Ω R31 = 275 / Rb = 275 / 10 = 27.5 Ω
