Question about balanced wye - delta connection

Click For Summary
SUMMARY

The discussion centers on calculating line currents in a balanced wye-delta connection with line impedance present between the wye source and delta load. The recommended approach is to convert the delta load to a wye configuration before performing calculations. This method simplifies the process of determining line and phase currents, as direct addition of line impedance to the delta load is incorrect without conversion.

PREREQUISITES
  • Understanding of balanced three-phase systems
  • Knowledge of wye and delta configurations
  • Familiarity with line and phase current relationships
  • Basic concepts of impedance in electrical circuits
NEXT STEPS
  • Study the process of converting delta loads to wye configurations
  • Learn about calculating line and phase currents in three-phase systems
  • Explore the impact of line impedance on current calculations
  • Investigate methods for analyzing balanced three-phase circuits
USEFUL FOR

Electrical engineers, students studying power systems, and professionals working with three-phase electrical circuits will benefit from this discussion.

i am confused on how to find the line currents when there is a line impedance in between the wye source and delta load... is it wrong to directly add the line impedance and the delta load without converting first the delta load to wye...? is there a way that i can find the line currents and phase currents...i know i cannot directly find the phase current on the delta load since there is a line impedance...plese help i am really having trouble on how to solve this kind of problem. Thank you in advance...

Hi
Simplest way to solve it ? convert delta (D) load to wye (Y) and then calculate line currents. Then go back to delta.
