Q

By what mechanism does a reverse-power relay prevent AC generator motorization?

🔍 Key Concepts

• Reverse power relay function in AC generator protection • What motorization of a generator means and why it is dangerous • Where protection devices act: generator breaker vs. main switch vs. load control

💭 Think About

• If a generator starts to motor instead of generate, what has to be opened or changed in the circuit to stop power from flowing into the machine? • Which device in a typical shipboard switchboard actually connects or disconnects an individual generator from the bus? • Would redirecting load or changing prime mover speed directly stop reverse power flow, or must the electrical connection itself be interrupted?

✅ Before You Answer

• Identify which component directly connects an individual generator to the bus (shared power system). • Confirm which device is specifically associated with protective relays like reverse power, overcurrent, and under-voltage. • Distinguish between a panel board main switch for the distribution panel and the generator’s own connecting device to the switchboard.
