🔍 Key Concepts

• Synchronizing AC generators before closing the breaker • Relationship between voltage, frequency, and phase when operating in parallel • Why phase rotation and phase angle matter in three-phase systems

💭 Think About

• If two generators are not synchronized, what will happen to the circulating currents and mechanical stress when the breaker is closed? • Is it enough that the meters show the same voltage and frequency, or do you also need to think about the timing and order of the phases? • In a three‑phase system, what does it mean if phase rotation is different between two machines?

✅ Before You Answer

• Check what must match for safe paralleling: voltage magnitude, frequency, and waveform relationship. • Verify whether phase sequence (rotation) must be the same for three‑phase generators. • Confirm if the instantaneous phase angle (relative phase position) between generators matters, not just the average frequency.
