Description
This mini eBook about electricity in ‘the grid' was originally published as a lengthy 10 page paper (with 7 figures and 1 table) in 2005.
If you’re not interested in electricity but never figured out what the words ‘sine’ and ‘cosine’ mean in math and still want to learn, you’ll be introduced to the ‘unit’ circle and 'magic' numbers (but you won’t learn geometry or trigonometry here).
If you’ve ever had problems with stray voltage, you’ll learn why balancing the loads in your systems is critical (and also why balancing loads helps save energy).
If you're unfamiliar with 180 degree out-of-phase versus 120 degree out-of-phase wiring and what it means to balance loads for either, this is an excellent read.
If you’re not a lineman or grid analyst or engineer, you’ll probably want to skip the sections on wye and delta connections (and for those of you who are … no, I don’t go through the math, BUT you may understand the system and connections better if you don’t know exactly why it’s important for banked transformers to have similar impedances.)
If you never could figure out how sine waves ‘fit into’ electrical flow and why the length of the wave allows the system to work, I expect this book will ‘enlighten’ you.
If you don’t know what the difference is between the amperage wave and the voltage wave and why you get more power when they peak at the same time, it’s worth a read but you won’t find any analysis of the amount of power lost if they are out-of-sync.
If the concepts of 'stepping up' and 'stepping down' voltage always confused you, you should come away with a greater understanding but you won't learn the physics of why a transformer works (there's not even a picture of one).
And, if you’re like me, you’ll read the whole paper, glean what you can from it and come back to the topics that didn’t make sense to you that you’re interested in and learn more about them in greater depth at a later date.
Oddly, I expect that one or two people might be interested in this paper just to see what is possible in terms of formatting a technical paper (in any field). I integrated the footnotes and comments on figures into the text in a way which I hope works well for readers while also allowing them to maintain continuity tied to the main text (using [tmt] = to main text).
