🔍 Key Concepts

• Use the three-phase power formula that relates kW, line voltage, current, and power factor. • Notice from the illustration that each main ship service diesel-generator (SSDG) is rated 2000 kW, 480 VAC, 3-phase, 60 Hz. • Remember that kW is real power and kVA is apparent power, and they are connected through the power factor (0.8).

💭 Think About

• First convert the 2000 kW rating at 0.8 power factor into kVA. What relationship links kW, kVA, and power factor? • Once you have kVA, how do you solve for line current (amps) in a 3-phase system given line voltage and apparent power? • After computing the current, which of the multiple‑choice options is closest to your calculated value?

✅ Before You Answer

• Be sure you are using the 3-phase formula: it should include $\sqrt{3}$ somewhere. • Confirm that you use line-to-line voltage (480 V), not line-to-neutral, in your calculation. • Double-check unit conversions so that kW → W and kVA → VA are handled consistently before calculating amps.
