AC Generators OBJECTIVES TERMINAL OBJECTIVE 1.0 Given the type and application of an AC generator, DESCRIBE the operating characteristics of that generator including methods of voltage production, advantages of each type, and methods for paralleling. ENABLING OBJECTIVES 1.1 STATE the purpose of the following components of an AC generator: a. Field b. Armature c. Prime mover d. Rotor e. Stator f. Slip rings 1.2 Given the speed of rotation and number of poles, CALCULATE the frequency output of an AC generator. 1.3 LIST the three losses found in an AC generator. 1.4 Given the prime mover input and generator output, DETERMINE the efficiency of an AC generator. 1.5 DESCRIBE the bases behind the kW and current ratings of an AC generator. 1.6 DESCRIBE the conditions that must be met prior to paralleling two AC generators including consequences of not meeting these conditions. 1.7 DESCRIBE the difference between a stationary field, rotating armature AC generator and a rotating field, stationary armature AC generator. 1.8 EXPLAIN the differences between a wye-connected and delta-connected AC generator including advantages and disadvantages of each type.
