Practice Questions - Section 5


            Instructions:
            The following questions are designed to give you the opportunity to practice for the EGSA Electrical
            Generator Service Technician Certification exam and to determine areas where you may need study
            and review.
            Once you have taken the practice questions, you can check your answers using a separate document
            from the ESGA Study Guide.  This document contains explanations for most of the correct and in-
            correct answers.  Task links are also provided with each question.  These links direct you to specific
            category and task areas.  From there, you can locate the text to use for reference on your specific area
            of need.


            Section 5 - Governors


            114.   Speed droop is?


                   a.     The difference between high idle and low idle engine speed
                   b.     The difference between unloaded and loaded engine RPM as measured by percentage
                   c.     The  RPM between unloaded engine speed and loaded speed
                   d.     None of the above

            115.   The engine speed is compared to a speed reference setting.  How fast the governor responds to an
                   error


                   a.     Rate
                   b.     Reset
                   c.     Gain
                   d.     Speed to voltage differential


            116.   Regarding a governor linkage, if each turn of the adjusting nut yields the same amount of movement
                   of the arm, the linkage has what type of adjustment?

                   a.      Direct
                   b.      Indirect
                   c.      Differential
                   d.      Linear

            117.   The output frequency of a magnetic pick-up is determined by:


                   a.      (# teeth/60)*rpm
                   b.      (rpm/60)*(rpm/#teeth)
                   c.      (#teeth*rpm)/60
                   d.      (rpm*60)/#teeth


            118.   One function of a governor is to monitor engine RPM, the other is to:


                   a.      Control the fuel flow
                   b.      Provide force to control engine speed
                   c.      Control engine speed by varying manifold pressure
                   d.      Control engine speed by varying the pitch of the cooling fan blades
