Delta to Wye Conversion (Delta to Star) Calculator

This delta to wye conversion calculator will help you transform a delta network of resistors to a wye network (or ‘Y” network).

In this calculator, you will learn:

• Basic types of resistor connection, difference between delta and wye networks of resistors;
• The formulas to be used when converting from delta to wye;
• Formula use to convert delta to wye networks
• Knowing how to our delta to wye conversion calculator.
• Some of the uses of delta and wye networks of resistors.

Read on to find out how to make this electronic circuit, symbolized with wye and delta diagrams, simple as a circuit with only parallel and series-connected resistors using delta to “Y”.

How to use the Delta to Wye (Δ TO Y) Conversion Calculator?

Using our delta to wye conversion tool is easier to use and calculate between delta to wye.

To determine delta to wye conversion

Please input the resistance values Ra, Rb and Rc for the delta network as shown in the figure below:

The delta to wye converter will then return the resistance R1, R2 and R3 of the equivalent wye circuit.

The default unit utilized for measuring the resistances is ohm (Ω).

Delta to Wye (Delta to Star) conversion Formula

R₁ = (R_b×R_c)/(R_a+R_b+R_c)

R₂ = (R_c×R_a)/(R_a+R_b+R_c)

R₃ = (R_a×R_b)/(R_a+R_b+R_c)

Where

R_a, R_b, R_c – Resistances in Delta Network

R₁, R₂, R₃ – Resistances in Wye (Star or Y) Network

What is the Application of Delta-Wye Transformation?

Resolving complex electrical circuits that contain resistors is accomplished through the application of the Delta-Wye Transformation method. It is common knowledge that these two types of connections

• Series connections and 
• Parallel connection

are the fundamental ones for connecting resistors.

After that, we will have an easier time obtaining the simpler equivalent circuit.
