Glossary
anode:The positive end of a diode or rectifier.blocking rectifier:Permits current flow in only one direction. This keeps the polarity of the exciter in the correct direction.bolted:Use of a bolt to hold two or more parts together.breaker:An automatic switch used to open a circuit.bridge:A circuit used to change AC to DC and to measure small quantities of current, voltage or resistance.build-up:(Voltage) A gradual increase.cathode:The negative end of a diode or rectifier.capacitance:The measure of a capacitors ability to take and hold a charge.circulating current:The flow of current between two generators working in parallel.commutator:A part of the shaft used to remove DC voltage for excitation.conduct:Give path for current flow.consideration:factor.continuity:A circuit that is not open.control:One that controls.controlled rectifier:A rectifier that lets current flow only after it has "turned on."DC controlled reactor:Gives resistance to current flow to the rectifier according to the voltage droop setting. Same as saturable reactor, DC.damping:To smooth out.de-energize:To stop current from going to a component.distribution winding:An arrangement of windings, in groups that are in several slots, that go from one end of the core to the other end.droop:decrease.effective:Gives the desired effect.elementary:simple.excitation:DC current (controlled) used to make a magnetic field.energize:To cause current to go to a component.electrostatic charges:Electricity caused by friction.exciter:Gives DC current to the field windings of the generator.field:Magnetic lines of force around a conductor caused by current flow.field windings:Many turns of wire wrapped around an iron core. When a DC current flows through the field windings it causes a magnetic field (like that of a bar magnet). 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 rectifer: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.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 suppresion:Reduce the cause of radio frequency interference.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. residual magnetism:The characteristic of a magnet after removal of excitation.saturable reactor:Acts as a valve, as load changes, valve opens or closes to give more or
