Which of the following statements best describes the operational characteristics of isochronous governors?

🔍 Key Concepts

• Isochronous governor vs droop governor characteristics • Relationship between speed and load for different governor types • Where isochronous governors are typically used in marine power systems

💭 Think About

• Think about what happens to the controlled speed when load increases on a unit with an isochronous governor: does the speed stay the same, drop a little, or drop in proportion to the load? • Which option sounds more like a description of a droop (speed-droop) governor rather than an isochronous governor? • Consider whether isochronous control is generally preferred for large main propulsion engines, or more often for generators that must hold a fixed frequency.

✅ Before You Answer

• Compare the phrase "constant prime mover speed for all values of steady load" with your understanding of isochronous control • Identify which choice clearly describes speed droop behavior and eliminate that first • Ask whether isochronous governors are known for good or poor sensitivity to speed changes at normal operating RPMs

Question 1 of 27070

Which of the following statements best describes the operational characteristics of isochronous governors?

They are suitable for use on main propulsion units.

They strive to maintain a constant prime mover speed for all values of steady load.

They cause a proportional drop in prime mover speed as the load is increased.

They have poor sensitivity at high RPM.
