🔍 Key Concepts

• Relationship between load current and excitation current in a compounded self‑excited alternator • How the reactor coils and capacitor bank feed PRI.1 in the excitation transformer • Difference between no‑load excitation and load‑responsive excitation

💭 Think About

• Look at where PRI.1 connects in the diagram: is it tied directly to the main stator output, or through the reactor coils that sense load current? What does that say about whether it is load‑dependent? • In a compounded alternator, when the ship’s load increases, do we want field excitation to increase or decrease to hold voltage approximately constant? How does that affect the wording of the correct choice? • Which winding in the excitation transformer (PRI.1 or PRI.2) is most likely to handle the basic no‑load excitation, and which is most likely to handle the compounding (load‑responsive) part?

✅ Before You Answer

• Verify whether PRI.1 is fed from lines that pass through the reactor coils, indicating a current‑sensing, load‑dependent function. • Check which option describes no‑load excitation only versus additional excitation that changes with load – remember compounded systems add excitation as load changes. • Confirm whether proper compounding means excitation varies in the same direction as load current (more load → more excitation) or the opposite direction.
