Single Line Diagram - Power Systems

AI Thread Summary
The discussion centers on the single-line diagram (SL diagram) used in Power System Analysis and Electrical Installations. Participants seek recommendations for books that cover this topic, noting that the diagrams are often referred to as one-line diagrams. It is pointed out that these diagrams simplify the representation of three-phase systems by depicting only one phase, which aids in analyzing connectivity and impedances without the complexity of illustrating all three phases. The conversation also touches on the educational context, questioning when these diagrams are first introduced in Electrical Engineering graduate programs.

Hey everybody,

Its recurrent in Power System Analysis and Electrical Instalations the SL diagram. I need recommendations of books in which I can read about it. I've done a little research but couldn't find anything. Thats amusing, in which classes are this diagram teached for the first time during the EE grad?

Not an expert on these, but I always knew them as One-line-diagrams. Maybe looking for that and Single-line will help.

Two references by Wikipedia.

They are called one line diagrams or single line diagrams. When you are dealing with a three phase system, it is a great deal simpler to just show one phase representation, which is what you have with a single line diagram. You can easily examine connectivity issues and impedances by just using a single line diagram without the need to draw in all three phases.
 

Thread '"WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians'

The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...

Thread 'Books with a more theoretical approach to turbulence and DNS'

I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
