If your organization has a subscription to IEEE standards you can access it online. Otherwise you can purchase it as part of the color books package.

The sheet is capable of calculating the medium line model, but you can set the suceptance equal to zero, which is what I was doing. You can mix in Magoo's equation, because it references the angle of the sending end that mine calculates and performs the calculation in reverse. His result is...

Yeah, that is why I had the user enter the current and voltage angles, so the sign could be used.as.needed. I will check that again. Thanks for the tip on the calculation errors, I was bound to miss something with all that activity. I had magoo's equation using the calculated voltage from the...

Thanks a bunch, needed that peer review to make sure i wasn't losing it!

The diagrams are actually straight out of IEEE, just there as a reminder to myself as I was working. My PF is leading because I am a generator considering what is happening further down the line. I am really just trying to relate the Short Tline model (the top part of the sheet) with the IEEE...

Yeah it does show the error, but what it doesn't show, even in their exact solution, (and the source of my confusion)is the couple percent of error you start to see as your lines get longer (more inductive). The main problem may be that I am trying to use the equation outside of it's...

Thanks for the tip on the paper, got a flight this weekend and I found it in the IEEE archives.

Thanks for the quick responses, you guys got me a nudge further down the path..... I kept working on the problem this afternoon and came up with the following...... My new assumption is this (or my new understanding of what IEEE assumption of Vdrop approximation is).... IEEE is calling voltage...

Hello All, I am having trouble rectifying an equation for voltage drop.... IEEE Red book states that voltage drop on a line can be calculated as Vdrop = IRcos(phi) + IXsin(phi) where R, X are the line impedance and phi represents the load angle. I is a magnitude. I am using the short TLine...

Thank you UMRPWR That is the exact issue I am running into. The lengths are pretty long on some of the sites and are almost unfeasible at times. We tried deep earth grounding as well, but the GEM entrenched radials seem to accomplish nearly the same effect for about half the price. You are...

Thank you for the outside the box solution to this issue. However my application requires that the resistance measured using the fall of potential method falls below 5ohms at the 62% distance mark. With out certified documentation of this fact, the wind turbine mfg warranty is null and void. I...

Hello All, I am currently working on a wind farm and we are running into some real issues with getting our towers grounded to the level required to keep a warranty with the turbine manufacturer. To combat this, I have proposed that we run copper at the same level as the warning tape beginning...
