Thank you for helping me regarding Power Factor. Oft times, my ignorance and my struggle to get past the misunderstanding of a concept is quite frustrating. If you wouldn't mind my taxing your patience a bit further, I'd like to exemplify my inferior understanding of Power Factor with an example, and ask a few more questions.
Let's say I purchase a unit of electronic hardware. Let's say this unit has a Power Factor of less than 1. So the electric utility company charges me, somehow ( by way of a power meter that measures kW-hours?). So I am charged by the Real Power that the unit uses, though the Apparent Power is required to be supplied by the utility company. If the difference between Real and Apparent powers is negligible, no big deal, apparently, for the utility company. I am undercharged according to the utility company's rate, so I assume that rate compensates for the Power Factor of most users.
Now let's say I implement thousands of these electronic units, and the utility company, by way of the increased demand on their generators, can no longer ignore the difference between my Real Power usage and my Apparent Power usage.
Q: Isn't it true that generators must take into account the Power Factor of the load they are supplying? Why not the same for an UPS system, whose battery-supplied direct current will be inverted to alternating current? Let's say my UPS system is rated for 200 kVA. If electronic equipment supplied by the UPS batteries has a certain load as well as a Power Factor of 0.7, then my UPS system can only support 140 W worth of the equipment, given that the Power Factor of the equipment tells me this equipment will cause higher current draw such that the power usage is
140 kW / 0.7 --> 200 kVA. Real Power = 140 kW, Apparent Power = 200 kVA
Q: Is there no meter that measures the extra current draw that would put this Power Factor issue to rest?
Q: When implementing a newly purchased electronic unit whose manufacturer has listed the Wattage on the unit, I can calculate the expense of running the unit from the Watt rating. Isn't the Power Factor of the unit also known by the manufacturer, and couldn't the Power Factor be included with the unit?
