a approx value of power factor which is acceptable in no energy losses — Preceding unsigned comment added by 115.248.112.54 ( talk) 13:33, 24 October 2017
This article doesn't make understandable what this power factor means or is supposed to be. It seems to indicate that "power" (whatever that means) somehow magically disappears because more current is being drawn from a supply than the device connected to the power supply receives.
In this case, I'm looking at a power meter connected to a Dell R320 server with 2x350W PSUs connected to a 230V supply, and the power meter says the power factor is 36 while the server is turned off. What the hell is that supposed to tell me? This article doesn't answer the question at all. — Preceding unsigned comment added by 2A09:8E40:352B:D900:D16B:872B:FFD5:6B7D ( talk) 05:01, 30 April 2022 (UTC)
The next question is why do they make PSUs that have such a low power factor? Do the PSUs they put into servers suck?
Of course this isn't a question and answer forum, as pointed out, but the topic must correctly answer the question of precisely what the topic is, and go beyond dictionary level.
If "time invariance" is a present factor in determination of the accuracy of the calculation, it must be mentioned as such. In fact, no specification of time frames are present. RMS is barely mentioned. Where multiple waves exist, are offset, and aren't even sinusoidal, time frames must of course be measured, calculated or specified!!! If power factor is calculated on a per-cycle basis, which cycle is it? If it is NOT calculated on a per-cycle basis, what is the averaging basis?
For some reason certain remarks ("the ratio of real power to apparent power") still exist over and over, but not in a problem / solution / proof format or presentation. In fact this wiki presently shows it is a collection of multiple, separate (and slightly conflicting!), pieces by multiple authors.
I hold no degrees, only some licenses which required some schooling, so I don't speak, and can't contribute, on the level of the main contributors here. I don't feel comfortable or capable of tackling the needed editing at this point. I'd call on the authors to do a bit of that. Tranzz4md ( talk) 18:03, 28 August 2022 (UTC)
It would be useful for the article to discuss the origins and "finding/discovery" of Power Factor. It might also be worth including in this Power Factor topic a write up of how scam companies use Power Factor to sell devices claimed to reduce your residential electric bill by up to 50% with a $40 device that contains nothing more than a less-than-$1 capacitor, and a less-than-$1 green LED in a $2 plastic housing that plugs-in to an electrical outlet. 2601:648:8100:C83:55A8:670F:C635:3E13 ( talk) 20:12, 24 April 2023 (UTC)
