good explanation. one little addtion, in most cases for example powerfactor corrction, you try not to go over 0.96 cos phi, bc you end up in resonance and voltages go out of control pretty fast, could cause arc over situations.
Great information. Thank you for sharing. I do have an oscilloscope....probably put it on to look at the harmonics of my power delivery and equipment. Always appreciate knowledge
The beer analogy is ok for most purposes but I'm not a huge fan of it for a few reasons: - Reactive power isn't billed by an energy supplier, you only pay for real power. Only some large industrial customers pay extra fees for reactive power for putting extra strain on the grid. - The "total beer level" in the glass is simply beer + foam, and to go from "total beer level" to "beer only" you could just subtract the foam from the total. But apparent power (kVA) isn't real power (W) + reactive power (kVAr). Instead it's: apparent = sqrt(reactive^2 + real^2). This is essentially the pythagoras'' theorem on a right-angle triangle, where the horizontal side is real power, the vertical side reactive power and the diagonal side the apparent power. The angle between the horizontal and diagonal side is "phi". (therefore cos(phi) is a multiplier to go from apparent to real power, aka the "power factor")
I only semi understood the beer analogy!! That was a fantastic walk through bro!! Smart shit that I have no clue what I’m looking at 😂 and I get lost in the details, but great explanation Especially for the residential guy 💪
It can seem confusing at first. The beer analogy is. You are paying for a full glass, including the foam, but you are drinking only the beer itself. So in essence.....the closer you can get to a full glass of beer without the foam, the less you need to accomplish the same task......getting faded 😆😆😆😆😆
