What is Multiline Diagram?

The multiline diagrams are representations of many systems, such as

  • Electric,
  • Fluid, and others,

And include all relevant details, such as

  • Terminals,
  • All phases,
  • Power and
  • Control system, and so on.

Multiline diagram is also called as three-line diagram, as it illustrates the connections to each component as well as displaying each individual circuit. In addition to that, each and every electrical component that is important to the system is depicted in this diagram.

As a result of this, an exhaustive multi-line diagram may be used to the process of compiling a bill of the materials for the electrical system. Each of the components that is included in the multi-line diagram has the potential to be given a characteristic that corresponds to a specific line component.

Function of Multiline diagram

  • A one-line diagram does not provide some information that are essential to three-phase circuitry, but those details are shown on a multi-line diagram.
  • The professionals with responsibility of plant maintenance & operations are able to understand how power systems work through the use of multi-line diagrams.
  • In addition to this, wiring diagrams for metering and protective relays can be developed with their multi-line diagrams.

Characteristics of Multiline diagram

  • A Multiline diagram is a representation of the components of a power system that uses the same standardised symbols as a single-line diagram, as well as a further collection of standard symbols that are additionally utilized in schematic and wiring diagrams.
  • A multiline diagram, as opposed to a single-line diagram, displays each component of the power circuit as a separate line.

What is the difference between the single-line and multi-line diagram?

Single Line Diagram Vs Multi Line Diagram

Single Line DiagramMulti Line Diagram
A component with one, two, or three connections is shown in a single line in a single-line representation.A representation consisting of many lines that displays the total number of electrical connections as well as the connection points for each component.
