Challenge 1 Hard

In a Star-Delta connected transformer, the secondary (Delta) side supplies power to an unbalanced load. Calculate the equivalent phase voltage if the line voltage is found to be 400 V.

💡 Hint: Use the relationship between line voltage and phase voltage in Star.

Challenge 2 Hard

Discuss how the absence of a neutral point in Delta connections can complicate system management in the event of fault conditions.

💡 Hint: Think of how issues propagate in interconnected systems.
