### Star to Delta and Delta to Star Conversion

### (Wye-Delta Transformations)

It is easy to calculate equivalent resistance of resistors which are in either parallel or series.Sometimes we may face difficulty in solving equivalent value. There we make use of**star to delta or delta to star conversion.**It is a powerful tool to simplify the complexity of the network. By applying this we can measurably reduce the problem solving time.

#### How To Identify Where Star Delta Transformation Is Required?

- Delta, or Δ (also known as the 'Pi' or π) configuration, and
- Star connected network which has the symbol of the letter 'Y' (also known as the 'T') configuration.
- In the below picture you can observe the connection of
**delta or 'Pi' configuration, star or 'T' configuration.**

Delta Configuration

Star Configuration.

####
**Delta (Δ) to Star (Y) Conversion **

In delta to star conversion, the delta connected elements will be converted to star connection in order to simplify the network analysis.Transforming from delta to star introduces one additional node.

#### Star (Y) to Delta (Δ) Conversion

In star to delta conversion, the star connected elements will be converted to delta connection in order to simplify the network analysis.Transforming from star to delta removes one node.

#### Star-Delta Transformation

#### Delta-Star Transformation

Star-Delta Transformation / Delta-Star Transformation can be used to any type of electrical component.Star to delta conversion formula have been given above.Delta wye transformation problems with solution pdf will be added (Stay Tuned).
