SR 4 GENERATOR
GLOSSARY
flashing: A process of putting DC current. from an outside source, into the field
windings to get residual magnetism.
fluctuate: change.
flux: Magnetic lines of force.
full wave rectifier: Changes AC to DC current.
gain: A change in quantity of voltage.
gate: An electronic part of a controlled rectifier (thyristor).
generate: To make electricity.
grounded: To make a connection to ground or to a component with similar effect.
impedance: A combination of resistances.
induced: caused.
interference: Mixture of signals.
instrumentation: Group of instruments.
insulated: A component with insulation.
induce (to): To send DC current to a coil and make a magnetic field.
C
layer wound: Method of placing a large wire (instead of four small wires as
in random wound) in uniform and parallel layers around a
generator rotor.
lead: wire.
line voltage: The output voltage of the generator.
lock in: When a contact closes to keep a solenoid energized.
lock out: When a contact opens to keep a solenoid de-energized.
magnetic: Having the characteristics of a magnet.
magnification: make larger.
module: An assembly of electronic components and circuits.
moisture: The water content in the air.
oscillation: A flow of electricity that periodically changes direction.
phase winding: Group of generator stator coils in which electric power for the load
is induced.
polarity: The positive or negative characteristics of two poles.
pulsating: Characteristic of rectified current similar to mechanical vibration.
radio suppression: Reduce the cause of radio frequency interference.
C
random wound: A method of placing four small wires around a generator
rotor. Each wire can cross the other while being wound.
reciprocating: Movement in a straight line first one direction then the other.
regenerative power: Power that works against the primary power.
reset: To put a switch in a ready condition.
