Question

Wye - delta connection:

a.) are affected by unbalanced loads and faults to a greater extent than other three - phase connections.
b.) are never affected by unbalanced loads.
c.) may use a floating wye - tie if procedures call for it.
d.) both A and C
e.) both B and C

Answer 1

Wye-delta connections can be affected by unbalanced loads and faults. They may use a floating wye-tie if necessary. Hence the correct answer is option D

Step-by-step explanation:

The correct answer is option D (both A and C).

Wye-delta connections can be affected by unbalanced loads and faults to a greater extent than other three-phase connections, making option A correct. This is because any imbalance in the loads or faults can result in uneven current distribution among the phases.

Option C is also correct as a wye-delta connection may use a floating wye-tie if procedures call for it. A floating wye-tie can help address issues of system imbalance.
