how to read panel drawings

Dear sanjeet.s

firstly tell me from which stream (mech/elect) u r ?

if u r from mech side u can purchase the basic electrical engineering drawing (by the writer SURJEET) of diploma level (ploytechnic)

try to learn as self as possible

surinder sharma

m from electrical backgrnd.m learning of my own but sometimes i get very much confused regarding the logic of the SLD's of the panels.I just want a very simple approac of looking at those electrical SLD.

i m from mech.

Can you end me a copy? And be a bit more specific about what you need to know.

i need how to read wiring digram basicaly for simple control pannel ( basic )

Please refer to the following CR4 Threads for free downloading: Piping and Instrumentation Diagram (P&ID), P&ID Design Guide and the following handbooks:Control and instrumentation, Electrical engineering.

I sure wish I had known about this thread last year when it occured... I am running a crew on top of a HRSG when I was handed over the reigns, I was given a P&ID and told to "familiarize myself with the drawings." Actually, it was drawings for all three systems on the platform Low, Intermediate and High Pressure systems. With the help of a few Pipe Fitters and Instrumentation guys (I am a Union Electrician), I am now somewhat fluent in this strange language of lines and symbols.

P&ID diagrams are very different from electrical diagrams. And in the realm of electrical diagrams, SLDs (Single Line Diagrams) are very different from Ladder Logic Diagrams, which are also different from Wiring Diagrams. The fact that you asked about understanding the "logic" of an SLD denotes the fact that you are in over your head. A Single Line Diagram is NOT a logic diagram...

These are the kinds of things you would learn in Engineering School. Self-taught is not a great thing in the electrical engineering world; there is an old saying that goes "There are old EEs and there are self-taught EEs, but there are no old self-taught EEs!"
