WHAT IS ELECTRICAL DRAWINGS? AND HOW ITS STUDY?
how to analyze and find electrical drawing to solve while troubleshoot its not a complicated just see the drawings
electrical drawing has many types there are
How many types of electrical diagrams are there?
Functional Diagram It refers to only a part of the
installation, being used to explain and understand the functioning of an
electrical circuit, allowing to interpret the diagram quickly and clearly,
through the graphic representation of all the components and conductors of that
circuit.
Multifilar Diagram It is used to perform a more detailed
representation of the electrical installation, showing and seeking more details
of the connections, components and conductors.
This diagram is little used for the interpretation of large circuits, due
to its complexity.
Unifilar Diagram It is the most used electrical diagram to
represent the electrical installation in a work, presenting the components and
the conductors' path in their physical positions, not allowing to easily
visualize the electrical current path.
This diagram also allows you to see how many conductors are passing
through the same conduit, the section of conductors and which circuit they
belong to.
Three-wire diagram Most used in electrical control systems
and three-phase machines, representing each of the 3 phases of an electrical
system, its derivations and connections.
Where the control and power circuits are represented separately, making
interpretation easy.
