Talk:Power factor
From Academic Kids
The article is confusing. What do the various values of the power factor mean? Are they the same (just magnitude) for both sources and sinks? A diagram with at least -1, 0, and +1 would be helpful. How does leading and trailing play into this? Do only sinks have leading or trailing characteristics or do sources too? Does the utilization depend on matching them, or is +1 always desirable for sinks no matter what the value of the source?
If this isn't the right place for comments about the entry I apologise in advance. Please direct me to the proper place.
I'm a rather bored power engineer, so i had a hack about, hopefully it makes a bit more sense now. let me know if it needs clearer explanation
Much better. It might be nice to illustrate the power triangle with something like the graphic at http://www.ibiblio.org/obp/electricCircuits/AC/AC_11.html.
This article only talks about "displacement" power factor. What about the effects of non-sinusoidal currents? --Wtshymanski 22:35, 16 Dec 2004 (UTC)
Non-sinusoidal (non linear)analysis is very difficult, and a bit too tricky to try and explain here. I have included some details about harmonics. --Euripides 15:53, 3rd Jan 2005
