Single-Line Drawings and Schematic Diagrams, Electrical Drawings and Diagrams Flashcards
a ? is a specific type of diagram with characteristics of its own and with a specific purpose.
schematic
? is normally used to describe a multipage, in-depth drawing of a project such as a substation.
Blueprint
A ? is an illustrative figure, sketch, or drawing that makes understanding easier.
Diagram
The most common diagram used in the electrical industry is the ? diagram
One-line
? that show the association of various components within the circuit.
Operator Lines
The single-line diagram is very simple and should be used to learn (in very broad terms) the function of each of the various components that are part of the total system. T or F
True
A ? (also known in the electrical industry as a circuit diagram) is a simplified pictorial representation of an electrical circuit.
schematic diagram
A ? normally shows the power and signal connections between the devices in order to show the functional relationship of the parts in a component, and in turn, the components in a system.
schematic diagram
The arrangement of the component interconnections on the diagram does not correspond to their physical locations in the finished device or circuit. T or F
True
Any portion of a device used to open a circuit or to introduce impedance into a circuit is called a(n) ? element.
Device element
The ? diagram shows the approximate relative location of devices
connection diagram
The schematic symbol for a cut-out resembles the symbol for a ? .
fuse
When a Qualified Electrical Worker needs to know the exact details of an item such as a transformer station, he or she should refer to a ? for the information.
specification book
When it is necessary to make minor changes, any blueprint used in the field must be redrawn.
T or F
False
