What are the 4 types of electronic diagram?

6.2: Types of Electrical Diagrams

  • Schematic Diagrams.
  • Wiring diagrams.
  • Block diagrams.
  • Pictorial diagrams.

What diagrams do electricians use?

Electricians rely on electrical floor plan (which is also an electrical diagram) for doing any building wiring. Engineers use various types of electrical drawings to highlight certain aspects of the system but the physical circuit and its function still remains the same.

What is a 3 line drawing?

Photo: NRC.gov. For a more detailed view of an electrical distribution system, a three-line diagram is used to show phase relationship. In polyphase AC systems, these drawings illustrate the various connections for A, B, C, neutral and ground – each represented with their own line.

What are the 3 main functions of electrical drawings?

An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.

What are the 2 types of wiring schemes?

5 Different Types of Electrical House Wiring Systems

  • Cleat Wiring. This wiring comprises of PVC insulated wires or ordinary VIR that are braided and compounded.
  • Casing and Capping Wiring.
  • Batten Wiring.
  • Lead Sheathed Wiring.
  • Conduit Wiring.

What are circuit breakers?

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

What is Riser diagram?

“ – [Instructor] Riser diagrams are usually a view of systems connections, such as fire alarm connections. Often times, these systems connect two devices throughout a building and incorporate more than one level or floor of the building. That’s where they get the name, riser.

What is an electrical 3 line diagram?

Three-line diagrams expand on the single-line by providing a basic visual guide for actual feeder cabling, instrument transformer connections, and protective devices. These drawings show how phases are wired and specific winding configurations without regard for their physical location.
