🔍 Key Concepts

• Look closely at the meter labels: voltage units, power factor, kW, and kVAR. • Remember which systems require power factor and reactive power (kVAR) measurement – AC vs DC. • Think about what kind of equipment would need two generators shown side‑by‑side with their individual kW and kVAR loading indicated.

💭 Think About

• Does the presence of power factor and kVAR meters tell you this is monitoring AC or DC machinery? • Which of the choices would normally be paralleled and load‑shared the way these two generators are shown? • Would a variable‑frequency MG set or an arc welder typically have this full set of distribution‑style meters for more than one generator, or is that more typical of a ship’s main power plant?:

✅ Before You Answer

• Verify whether DC systems have power factor or kVAR – would those meters make sense on a DC generator? • Check which options normally operate at around 450 volts on a shipboard system. • Confirm which option would need detailed load and reactive load sharing between two units on a switchboard.
