Question 1 of 27070

Diesel engines driving alternators operating in parallel must maintain a set frequency regardless of load changes. The governor characteristic used to accomplish this is known as __________.

🔍 Key Concepts

• diesel engine governors and how they control speed with changing load • difference between maintaining constant speed/frequency vs merely reacting quickly • which governor characteristic relates to holding RPM steady under varying load

💭 Think About

• Ask yourself: which term describes the governor’s ability to keep engine speed (and therefore generator frequency) essentially constant when the electrical load increases or decreases? • Think about how alternators in parallel must behave—what happens to the system if frequency changes when one generator takes more load? • Match each option’s word meaning to governor behavior: which one is about steady control under load, rather than speed of response or small movement detection?

✅ Before You Answer

• Verify which characteristic of a governor is defined as maintaining nearly constant speed under varying load. • Eliminate any terms that mainly describe how fast a governor responds instead of how well it holds a constant speed. • Confirm which term is linked in your notes or textbook to parallel operation of AC generators and frequency control.
