🔍 Key Concepts

• Relationship between engine speed and generator frequency/voltage • What happens to mechanical and electrical parts when they are driven above design speed • Protection devices: which ones protect against electrical conditions vs mechanical damage

💭 Think About

• When the diesel engine overspeeds, what happens immediately to the generator’s rotor and the mechanical stresses on it? • Which of the choices describe protective trips that would open the breaker, and which describe a physical consequence to the machine itself? • Does overspeed make the generator produce less voltage, reverse power, or does it mainly affect the mechanical integrity of the generator components?

✅ Before You Answer

• Identify which options are protective trips (relay actions) and which are mechanical outcomes • Ask: Does overspeed normally cause low voltage or the opposite effect? • Consider which effect would be most directly caused by running the generator above its design speed for even a short time
