🔍 Key Concepts

• Reverse-power relay purpose in generator and motor protection • How an AC generator (alternator) can be accidentally driven as a motor if system conditions change • Typical protection applied to prime movers vs. auxiliary equipment in a shipboard electrical plant

💭 Think About

• Think about which device, if it started taking power FROM the bus instead of delivering it, could physically try to ‘drive’ the machine in the wrong direction. • Ask yourself: on a ship’s electrical system, which of these components is actually connected directly to the power bus as a source of power? • Consider which items are mainly control/auxiliary components and which is the main power-producing device that might need reverse-power protection.

✅ Before You Answer

• Identify which option is the main AC power source tied to the ship’s switchboard. • Eliminate devices that are only for control, excitation, or signal transmission, not for delivering large amounts of power to the bus. • Verify which equipment, if motored, could damage the prime mover (diesel, turbine, etc.) and therefore requires reverse-power protection.
