On two sides of a 3-\(\phi\) star / delta transformer the
On two sides of a 3-\(\phi\) star / delta transformer the
Show Hint
Star-delta transformers introduce a 30° phase shift in both voltage and current.
Updated On: May 23, 2025
- Voltages differ by 60° and currents differ by 30°
- Voltages differ by 30° and currents differ by 60°
- Both voltages and currents differ by 60°
- Both voltages and currents differ by 30°
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- In star-delta or delta-star transformers, a 30° phase shift occurs.
- The phase difference affects both voltage and current phasors accordingly.
- The phase difference affects both voltage and current phasors accordingly.
