🔍 Key Concepts

• Primary vs secondary windings – are they separate, or is there a common winding used for both? • How an autotransformer is drawn compared to a transformer with isolated primary and secondary windings. • What a dual-voltage secondary looks like (number and labeling of X‑terminals).

💭 Think About

• Look closely at how many distinct windings are shown on the secondary side and how many X‑terminals are brought out – what does that usually indicate? • Is there any point where the H‑side (primary) and X‑side (secondary) windings are actually the same conductor, or are they completely isolated? • Do you see any indication of a three‑phase connection (like delta or special phase‑shifting) in this single diagram?

✅ Before You Answer

• Verify whether the primary and secondary are magnetically coupled only (separate coils) or electrically connected (shared winding). • Count the number and labeling of X‑leads (X1, X2, X3, X4) and decide what configuration that normally represents in single‑phase transformers. • Confirm that nothing in the figure suggests a three‑phase connection such as open‑delta or Scott connection in this single unit.
