Applications of Star to Delta Conversion

  • Its common application is to analyze and simplify complex circuits. It thus helps in easier calculation and less time consuming methods.
  • It is used in power distribution systems, where loads are connected in either star or delta connection. Depending on the parameters the connection type is fixed. The conversion method gives the flexibility in changing the connection type as per requirement and analysis.
  • It is used in impedance matching of a load with source which helps in optimizing the efficiency of power transfer.
  • It is used in three-phase motors where the conversion method gives the flexibility of changing the connection type depending on the scenarios.

Conclusion

Star and Delta are two types of connections that are used to simplify and analyze complex electrical circuits. They are mainly implemented to the three phase networks and are widely used for power distribution and circuit design. The process of expressing the resistances of delta connection in terms of star provides three equations to convert a star network into a delta network. This technique is quite useful as it gives the flexibility of changing the connection type as the required parameters. Although it is very useful but there certain limitation as well which includes it being mostly limited to three phase networks....
