Question 1 of 27070

DC generator circuits are protected against malfunctions due to prime mover power loss by the use of what device (or devices)?

🔍 Key Concepts

• Protection of DC generators when the prime mover fails or slows • Function of a reverse current relay in a DC system • Difference between DC reverse current protection and AC reverse power protection

💭 Think About

• Which device prevents the generator from being driven as a motor and discharging into the bus if the prime mover power is lost? • In DC systems, what specific relay looks at current direction between the generator and the bus? • Which listed device is normally associated with AC alternators and prime movers, rather than DC generators?

✅ Before You Answer

• Identify which option specifically monitors direction of current flow in a DC circuit • Confirm which device opens the circuit automatically when current reverses, protecting the generator • Verify which relay type is commonly associated with AC reverse power rather than DC reverse current
