Generator Glossary: Key Terms & Definitions
Electrical generator that produces alternating current (preferred term). Aka alternator.
AC power with a unity power factor. Measured in watts.
Circuit breaker contacts open to the air (atmosphere); see also circuit breaker.
Electrical generator that produces alternating current (non-preferred term).
Windings embedded in the pole face of a synchronous generator, whose function is to dampen oscillations of the pole due to cyclic irregularity and effect of load changes.
The unit of electrical current (amp).
Controls using variable voltage or current to pass information.
The product of current and voltage in an alternating current circuit which has a reactive element.
The assembly of windings and iron core in which the generator output is produced. Sometimes referred to as the Stator to avoid confusion.
Term applied to motors or generators which operate at a speed not fixed by poleage and the supply frequency.
Devices for reduction of the emission of sound (also known as silencers).
Transformer switching arrangement to reduce voltage applied to an electric motor during starting.
A device used to automatically switch a power supply from normal to emergency when a power failure occurs.
AVR voltage reference is reduced as load increases.
