Description
Course Title
Mastering Single Line Diagram
Covering Low Voltage AC, Low Voltage DC, Medium Voltage & High Voltage Single Line Diagrams.
Course Details
Welcome to the course of "Single Line Diagram". In power engineering, a single-line diagram (SLD), also sometimes called one-line diagram, is a symbolic representation of a three-phase electric power system.
The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. Instead of representing each of three phases with a separate line or terminal, only one conductor is represented.
Whenever it comes to start new project, define scope of work, Single line diagram is always the most important document to consider & prepare. Furthermore single line diagram is also required to prepare shutdown / maintenance method statement.
