70% to passWhich of the listed figures shown in the illustration represents a three phase transformer connected in a wye-delta configuration? Illustration EL-0084
A1
B2
C3
D4
AI Explanation
The correct answer is D. The illustration EL-0084 depicts a three-phase transformer in a wye-delta configuration, which is represented by figure 4. In a wye-delta configuration, the primary windings are connected in a wye (Y) configuration, while the secondary windings are connected in a delta (Δ) configuration. This type of transformer connection is commonly used to step down voltage levels and provide a neutral point for the system. The other answer choices (A, B, and C) represent different transformer configurations, such as three single-phase transformers or a three-phase transformer in a delta-delta or wye-wye configuration, which are not the correct representation of a wye-delta transformer.
