i love the way that you explain everything with your words and visuals! I graduated from electrical school but waited too long to take my JW test. Wanted to brush up on a few things before my 2nd attempt and am so glad that i found your videos! Amazing job sir!! and TY!!
THIS GUY IS GREAT. I just went to school about the operating theory of the buck boost transformer i am about to install on my inverter heat pump which blew up its main board that is rated on the AC supply at 208-230VAC and where my FPL power from the utility is typically 247 and has gone up to 262. Now at least i fully understand what it is doing in wiring diagram I. By the way i am working with an Acme Electric T113074. The only thing that yet troubles me is that the wire coming into the AC supply south of the AC fuse box (60A fuses) where the AC is rated at 50A max (typically 20A or even less due to 1/3HP scroll compressor motor), well the wires are 8 gauge or so, and the wires in the buck boost appear to be only 12 gauge, which say they are good for 20A and not 50A. Anybody know why the buck boost that is correctly specd out and purchased for 50A max are so thin? Also, what is the best way to connect fat low gauge wire, 8 or 10 gauge, to 12 or 14 gauge wire? Should i solder or use wire nuts? I don't necessary expect a reply to my post so in the meantime let me thnak Dave Gorodn for a great video!!!
Hi good morning sir This is Mardorine writing from Cameroon. My question is if the value of the inductor or that of the active reactance was not given. How then will the inductance be calculated ? Given that the angle has been provided ?
Dave, I had to watch your video several times to be sure I was hearing right. Your explanation of the secondary is good but the primary is backward. To decrease the secondary voltage, you have to add turns to the primary. Tapping the primary will raise the secondary voltage. If you tapped the primary down to the same number of turns there are in the secondary, it would be a one-to-one transformer and the output would be 120v. Your formula says it all: to decrease EsubS you have to increase NsuP.
I thoroughly appreciated your lecture, but to make it crystal clear you need to another board or more slides. Very informative and for that i appreciate you .
In the delta transformer, only A to B windings are directly connected to the line voltage of 480 volts. The B to c and A to B windings are connected to the line voltage of 480 volts through a line winding in series with it.
Yes, you do explain well, but your demeanor is that you are talking down to preschool children. I keep waiting for you to say "today boys and girls" or for you to look into the camera and say "I see Billy and Susan, and Tommy, etc...
