🔍 Key Concepts

• Behavior of synchronous motors when they lose step with the generator • What kind of mechanical vs electrical symptoms you would observe on a turbo‑electric drive • How protective devices and interlocks respond when a large propulsion motor is no longer properly synchronized

💭 Think About

• Ask yourself: if a synchronous propulsion motor slips out of step with the generator, would the first obvious sign be electrical protection operating, mechanical motion, or gradual heating? • Consider which option describes an immediate and direct consequence of loss of synchronization, rather than a possible later effect or unrelated symptom. • Think about whether loss of synchronization would show up more clearly in motor/generator electrical relationships or in general ship behavior like hull vibration.

✅ Before You Answer

• Identify which choice is most directly tied to electrical synchronization between generator and motor, not just general machinery trouble. • Eliminate any option that sounds like a slow-developing condition (e.g., takes time to heat up) instead of an immediate indication. • Check which option involves a protective response or circuit condition that would change quickly if the motor were no longer in sync.
