VALVE GP-CHECK 3270376 - Caterpillar

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 direct current (DC) to the field windings of the generator.Field - A field is a magnetic line of force that surrounds a conductor. This force is caused by current flow in the conductor.Field Windings - Field windings are many turns of wire that are wrapped around an iron core. When direct current (DC) flows through the field windings, a magnetic field is produced. This magnetic field is comparable to the magnetic field of a bar magnet.Flashing - Flashing is a process of putting direct current from an external source into the field windings. This process causes the generator to produce an output voltage.Flux - Flux is magnetic lines of force.Frequency - Frequency is the number of cycles that are completed in a one second period. The unit of frequency is the Hertz (Hz). One hertz is equal to one cycle per second.Full-Wave Rectifier - A full-wave rectifier changes the positive phase and the negative phase of alternating current to direct current.Gain - Gain relates to the ratio of input magnitude to output magnitude.Gate - A gate is an electronic part of a controlled rectifier (thyristor).Generate - The production of electricity.Grounded - A device is grounded by making a connection to ground. A device could also be grounded by making a connection to a component that is connected to ground.Hertz (Hz) - Hertz is the unit of measurement for frequency. One hertz is equal to one cycle per second.Humidity - Humidity is the water content that is present in the air.Impedance - Impedance is the resistance to alternating current.Impulse Modulation - Impulse modulation changes the following characteristics of a wave: amplitude, frequency and phase. This is accomplished by impressing one wave on another wave that has constant properties.Induce - This refers to the transfer of power from one device to another device. The transfer is done via a magnetic field or via an electric field.Interference - Interference is an unwanted mixture of electrical signals. Interference is usually associated with electrical noise.Instrumentation - Instrumentation is a group of instruments that are used for measuring a system function.Insulated - An insulated device is a device that is covered with a nonconductive material.kVA - This is the abbreviation for Kilovolt Amperes. kVA is a term that is used when electrical devices are rated. In order to calculate a device's kVA rating, multiply the rated output (amperes) by the rated operating voltage. KVAR - This is the abbreviation for Kilovolt Amperes Reactive. KVAR is associated with the reactive power that flows in a power system. Reactive power does not load the generator set's engine. Reactive power will cause thermal loss in the generator.KVAR Regulation - KVAR Regulation is one of the two methods that are used to regulate the reactive power output. Regardless of the generator's real power output, the voltage regulator causes the generator to produce a
