Faraday rotor

A typical excitation system includes a voltage regulator, or exciter, protection circuits, and measurements transducers. If the terminal voltage decreases below rated value, the conU ol system increases the rotor cuiTent and thus the magnetic field as shown in Faraday s law, the generated voltage is thus forced up to the desired value.
