SHAFT-LH 8Y1082 - Caterpillar

Actuate - Actuation relates to putting something in motion.Anode - An anode is the positive end of a diode or an anode is the positive end of a rectifier.AREP - Auxiliary winding regulation excitation principle. The internal excitation auxiliary windings are embedded in the slots in the stator. The AREP windings provide power to the voltage regulator.Armature - The armature refers to the winding of a generator that produces a voltage when the armature passes through a magnetic field. The armature is the winding that generates the voltage that is converted from the mechanical power that is applied to the generator. In a brushless AC generator, the main stator winding is the armature winding. In a brushless exciter, the rotor is the armature of the exciter.AVR - Automatic voltage regulatorBlock Load - A sudden addition or removal of the generator load. A block load can be a partial block load. A partial block load is expressed in percentage of the generator set rated load. A full block load means 100% of the rated load is applied in one step.Bridge Rectifier - A bridge rectifier is a circuit that is used to change alternating current (AC) to direct current (DC).Buildup - A buildup is a gradual increase in voltage.Cathode - A cathode is the negative end of a diode or a cathode is the negative end of a rectifier.Capacitance - Capacitance is the ability to store an electrical charge.Capacitor - A capacitor is a device that will store an electrical charge.CDVR - Caterpillar digital voltage regulator.Circuit Breaker - A circuit breaker is an automatic switch that is used to open a circuit.Circulating Current - Circulating current is the flow of current between two or more generators that are working in parallel. Circulating current is also the flow of current between two or more generators that are parallel with a utility line.Conduct - Conducting relates to allowing the flow of current.Continuity - Continuity provides a path for current flow.Control - A control is a device that controls another device. A control is also a circuit that controls a device.Direct Current (DC) - Direct current is current flow that moves in only one direction in a given circuit.Damping - Damping refers to decreasing the amplitude of a signal.De-energized - A de-energized input refers to stopping the current that is going to a component.Droop - Droop refers to a decrease.Excitation - Excitation is controlled direct current (DC) that is used to make a magnetic field.Energized - An energized input refers to activating a device.Electrostatic Charge - Electrostatic charge is electricity that is caused by induced voltage and stored charge.Exciter - An exciter supplies alternating current (AC) to the diode rectifiers. The diode rectifiers supply direct current (DC) to the main rotor windings of the generator.Field - A field is magnetic lines of force that surround a conductor. This force is caused by current flow in the conductor.Field Windings - Field windings consist of wire coils that are wrapped around an iron core.
