GLOSSARY - CONT
CONDUCTOR
-
A wire, cable, bus, or other device intended to distribute current from
the supply to the load. Technically, a conductor is any device which
will permit the flow of current.
COOLANT
-
The circulating element, generally fresh water, which carries away the
head generated by the friction of moving parts of an engine.
CURRENT
-
The flow of electrons in a circuit forced by an applied voltage potential
(See Alternating Current and direct Current).
CYCLE
-
A complete set of events before repetition occurs. In alternating
current or voltage, a cycle starts at zero, continues to a maximum
positive value, returns to zero, continues to a maximum negative
value, and is completed at zero.
EXCITATION
-
The direct current input to the field coils of a generator which produces
the magnetic flux required for inducing voltage into the generator
stator coils.
EXCITER
-
An electrical device used for supplying the excitation to the generator
field (see Exciter Rotor and Exciter Stator).
EXCITER CURRENT
-
The direct current supplied to the exciter field coils which is controlled
by the voltage regulator.
EXCITER ROTOR
-
The rotating member of the exciter into which a three-phase alternating
voltage is induced. The resulting ac is then rectified into direct current
and applied to the rotating generator field windings.
EXCITER STATOR
-
The stationary member of the exciter which serves as the exciter field
producing the magnetic field from the direct current supplied by the
automatic voltage regulator.
FIELD
-
current, will produce a magnetic field. The exciter stator serves as the
exciter field while the main generator rotor serves as the generator
field.
-
The number of complete cycles of alternating current per unit of time.
Typically, frequency is expressed in cycles per second or Hertz (Hz).
