Delta-Star Conversion Calculator

Delta-Star Conversion Calculator

Convert a three-phase delta network into its equivalent star network.
For a balanced Wheatstone bridge, the star resistances are given by:
\[ R_a = \frac{R_{ab}\,R_{ca}}{R_{ab}+R_{bc}+R_{ca}},\quad R_b = \frac{R_{ab}\,R_{bc}}{R_{ab}+R_{bc}+R_{ca}},\quad R_c = \frac{R_{bc}\,R_{ca}}{R_{ab}+R_{bc}+R_{ca}} \]

* Enter all resistor values in ohms.

Step 1: Enter Delta Resistor Values

Example: 100 Ω

Example: 150 Ω

Example: 200 Ω

Formulas:
\( R_a = \frac{R_{ab}\,R_{ca}}{R_{ab}+R_{bc}+R_{ca}} \)
\( R_b = \frac{R_{ab}\,R_{bc}}{R_{ab}+R_{bc}+R_{ca}} \)
\( R_c = \frac{R_{bc}\,R_{ca}}{R_{ab}+R_{bc}+R_{ca}} \)
