So, we've got some small generators with no AVR or governor where the operators control every generator function. Long story short, it's become apparent the operators need a refresher in what "power factor" is and how it effects the units, and it's fallen on me to try and write a tutorial for them.
Ironically, it's also a topic that has a bit of mystery for me, but I did the best I could. :blink:
I'm looking for two opinions:
Electrical wizards:
Are there any unforgivable technical errors? Keeping in mind, I took a lot of liberties to try and make it very simple (like not even mentioning leading PF). These guys ain't electricians, let alone engineers.
The amateurs like me:
How easy do you find this to understand? Is there anything I can clarify or explain better?
I'll put it this way, John. It seems to illustrate the point better than just the words then the instructor just throws the trig at ya! A lot of folks get confused when angles enter the picture, and a lot of instructors out there have problems with being that "down-to-earth" when trying to illustrate things like that.
Its pretty clear (granted I'm studying this right now in school too), the way you have laid it out.
Depending on your goal, I would say that the last page would suffice depending on your target audience. What I mean by that is that some, IMO, will be better off following rules than working on theory. Adding the theory may just complicate things for some (read: "I don't know how it got in the bottle but I put this stuff on hot dogs").
Either way the info is there and it reads clearly.:thumbsup:
I got all the way through it, and as soon as I'd finished the last page, I realized I could've just said "Watch the amps, dammit!" and it would've served the purpose.
I'm sorta hoping it'll be a "teach a man to fish" kinda thing.
Doesn't your generator system have a demand meter and give you a KVA reading? If it did, all they have to do is watch that and make sure you're within your range, like you said, "watch the amp".
I like your example with the elephant and train. I'm stealing it next time I've got to teach power factor to the second years. :thumbup:

I think it's great! I haven't studied that yet and havent had to learn it in the field but I feel pretty educated now. Would you mind emailing this to me?
