This lesson describes generator construction and explains some of the principles behind generator operation and process control. • Identify the difference between induction and synchronous types of three-phase generators • Recall the construction of a three-phase, two pole DC generator • Recall how a sinusoidal waveform illustrates the number of amps produced over a given time • Recall the operation of a synchroscope • Identify the parameters to be controlled when placing the generator on the electrical grid
