This is accomplished by the generator excitation system. The excitation system monitors the generator output and regulates the magnetic field to maintain the desired voltage. As the load on the generator is increased, an increase in current flow causes the voltage to drop.
Whenever the generator is running, always assume and proceed as if voltage is present at the generator leads and at the regulator panel connections. Caution must be observed. Otherwise, serious personal injury or death can result. Before any work is done, and testing is conducted appropriate measure should be taken to prevent
