Understanding Electrical Diagrams And Control Circuits

Topology (electrical circuits) - Wikipedia
Circuit diagrams. The circuit diagrams in this article follow the usual conventions in electronics; lines represent conductors, filled small circles represent junctions of conductors, open small circles represent terminals for connection to the outside world. In most cases, impedances are represented by rectangles. A practical circuit diagram would use the specific symbols for resistors
Three Phase Motor Star/Delta - ELECTRICAL TECHNOLOGY
3-Phase Motor Connection Star/Delta (Y-Δ) Reverse-Forward & Up-down without Timer Power, Control & Wiring Diagrams. In this motor starter, there are four Contactors and switches (Two ON-Push and OFF-Push) are used to change the rotating direction of a three phase motor such as Revers, Forward, Up or down. As there is no timer used in the control circuit, the operation is semi-automatic or manual.

Three-phase Y and Delta Configurations - Electrical
Three-phase Wye (Y) Connection. Initially we explored the idea of three-phase power systems by connecting three voltage sources together in what is commonly known as the “Y” (or “star”) configuration. This configuration of voltage sources is characterized by a common connection point joining one side of each source.

Electrical And Electronic Symbols | Electrical4U
Feb 24, 2012An electrical symbol is a small image used to represent an electrical or electronic device or function. They are also known as circuit symbols or schematic symbols as they are used in electrical schematics and diagrams. Some basic electrical symbols include: Wires; Diode; Batteries; Transformers; Capacitors; Resistors; Inductors; Fuses; Switches; Bipolar Junction Transistors
Y-Δ transform - Wikipedia
The Y-Δ transform, also written wye-delta and also known by many other names, is a mathematical technique to simplify the analysis of an electrical network name derives from the shapes of the circuit diagrams, which look respectively like the letter Y and the Greek capital letter Δ circuit transformation theory was published by Arthur Edwin Kennelly in 1899.
