PGG-EG Governor/Actuator
For Electrical Generation Application

PGG-EG governor/actuators have motor speed setting of the ballhead backup governor. The units are normally used on generator applications. Externally adjustable droop on the backup governor and load limit are standard on the PGG-EG.

Setting the speed of the mechanical governor slightly higher than the maximum speed under electronic control causes the mechanical portion of the PGG-EG to always seek a fuel setting higher than the electronic control. Electrical control thus controls the fuel position because of the least-fuelselection feature.

Should the electronic signal to the reverse acting PGG-EG fail, due to some problem in the system, the electric actuator will call for an increased fuel position, above the setting of the mechanical governor. At this point the mechanical speed setting is lower, and the ballhead controls the engine-fuel setting.

PGG governor/actuators are available with any of the PG output systems. Output ranges from 16 N m (12 lb-ft) maximum work capacity to 678 N m (500 lb-ft), depending on the governor operating pressure and the output options selected. Most outputs provide 30° of rotary travel (25 mm [1 inch] of linear travel is also available).

PGG-EG governors may be equipped with lube oil pressure and water pressure alarm and shutdown.
