DWye to Delta (Star to Delta) Conversion formula
The Wye to Delta (Star to Delta) Conversion Calculator allows engineers, students, and technicians to convert a Wye
(Star) network of resistances or impedances into its Delta (Δ) equivalent. This conversion is commonly used in
three-phase circuit analysis, load balancing, and network simplification.
Formulas for conversion:
Delta Resistances (Ra, Rb, Rc)::
\[ R_{a} = \frac{R_1 + R_{2} + R_{3}+R_{1}\times R_{3}}{R_{3}} \]
\[ R_{b} = \frac{R_1 + R_{2} + R_{3}+R_{1}\times R_{3}}{R_{1}} \]
\[ R_{c} = \frac{R_1 + R_{2} + R_{3}+R_{1}\times R_{3}}{R_{2}} \]
Where R1, R2, R3 are the Wye resistances.
This calculator provides quick and accurate results for resistor, reactance, or impedance values, making three-phase circuit analysis easier and reducing manual calculation errors. It is suitable for DC or AC three-phase systems.
