Which outcome occurs when unbalanced load is connected in a three-phase delta-wye distribution transformer?

💡 Explanation

When unbalanced loads are connected to a delta-wye transformer, a circulating current is induced in the delta winding because the differing phase impedances create voltage imbalance. Therefore, circulating currents occur, rather than voltage reduction, harmonic resonance, or saturation, which require different imbalance conditions or harmonic sources.
