🔍 Key Concepts

• Parallel operation of alternators – what conditions must match before closing the breaker? • Difference between real power (kW), current (amps), reactive power (kVAR), and number/relationship of phases. • Meaning of synchronism in three‑phase AC systems.

💭 Think About

• When two alternators run together, which condition—if it is NOT matched—would cause very large circulating currents the instant you connect them? • Think about what the synchroscope and phase‑sequence indicator actually check before you parallel an alternator. • Which of the choices is a system condition that must be correct before paralleling, rather than something you adjust or share after they are already paralleled?

✅ Before You Answer

• Identify which option describes a fixed electrical relationship rather than a load‑sharing outcome. • Ask: which of these is normally checked with synchronizing lamps or a synchroscope, not with ammeters or kilowatt meters? • Eliminate any options that mainly relate to how load is divided after the machines are already safely in parallel.
