Gordon I wish I had your videos in the 90's where I was learning in my technical college in Poland. Because of the materials which you produce is so easy to undesrsted electric principles. In the 90's I had to learn from the books and somtimes it took me so long time to undestand and make sure that I undestend correctly a lot of these principles which you showed. What you made is incredible just only few minutes isteead of months or years is needed to learn the same quantity of materials. Your materials should be provided to many many schools in the world as the basic curruciulum. Best regards Piotr

I’ve always thought of voltage level induced into the secondary as simultaneous overlapping voltage addition & subtraction (ac) for each winding, equaling out to the total amplitude of the induced sinusoidal waveform. I like the series battery analogy better though because it’s easier to picture & understand, even with the DC distinction. Clicked with my brain anyhow, so thanks!

Hello Dave. Just wanted to say how great I think your channel is. I'm a college lecturer in electrical installation here in the UK and I would love to build something like that so I can demonstrate transformer theory to my students. I don't suppose you would be interested in sharing the specs on that at all? Our cable sizes are metric here and our single-phase voltage is 230V, so I would have to make certain adjustments. Would be great to talk to you if possible. All the best.

Built a pulse motor using coils and a magnetic armature that has run a year and maintained the battery voltage.

@stevewinwood367410 ай бұрын
Does winding the coil one way versus the other way determine which side will be "positive"? I.e. the meter was reading positive voltage. If you had left leads on same ends but taken entire coil off and flipped it before putting back on would it have read negative? Course it being AC might throw things a bit. But I think you kind of addressed what I am trying to figure out when you talked about phase. So maybe one direction of secondary is in phase or positive same time(excluding lag) and an opposite wound secondary would be out of phase or negative when primary positive?

Dave, how could one get 120 in each phase to neutral from a 3 phase source from a delta connection??? Without having a high leg... i saw a delta Service 120 each phase to neutral and 240 between phases shouldnt it be higher one phase? What equipment could be between tranformer and panel?
@awxomexd Жыл бұрын
In a 3 phase delta, the line voltage magnitude is equal to the phase voltage magnitude. If you have a 240Vphase delta transformer with a center tapped transformer on one of the legs, you can get 120V with respect to the neutral on that phase. Some complicated math for the other leg that does not have the center tap with respect to neutral, but it would end up being 73% higher. (multiply by sqrt 3).
@davegordon6819 Жыл бұрын
Hi Ivan, Thanks for asking, but I haven't seen a scenario that you describe, and thank you to "A V" for replying with the math for a high-leg delta. You should see about 208 V from the high-leg to neutral. I suppose someone could take that 208 V (high-leg phase wire and neutral wire) to a single-phase transformer and transform it down to 120 V, but this is probably highly unconventional and could have unintended/negative consequences depending on how the transformer connections are made and if the other phases or the center-tapped neutral from the original delta transformer were accidentally connected to the "neutral" (not really a neutral, but potentially a grounded conductor) from the single-phase transformer. I it were going to a panel this would likely be the case. For starters, you may end up with current finding its way back to the delta through the single-phase transformer by traveling on the ground conductor between the two transformers. I have never seen the high-leg used for single-phase 208, but I have heard that some people say they have. There may be something out there like what you're describing, but I haven't seen or heard of it.

With most transformers that have a magnetic core, including yours, doesn't the core suck up all the magnetic field? That is, like 99% + of the flux lines are in the transformer's core? And if in theory, in order to induce an emf you need a wire, and a magnetic field, and relative motion. When the wire "cuts through" the magnetic field lines it induces an emf. So if 99%+ of the magnetic flux lines are contained in the core of the transformer, which magnetic flux lines are "cutting through" the wire to induce the emf? I realize this is a different type question, but it seems that there is a conflict between the theory here to me. Any thoughts? Thanks
@Aadil41290 Жыл бұрын
consider it from the corollary of Amperes circutal law. if there is alternating current passing a straight wire then there is alternating magnetic flux around. Now if there is alternating flux through a straight path then there is alternating voltage around it. Same happens in case of eddy currents. just a crude explaination.
@djimms5644 Жыл бұрын
@@Aadil41290 But a transformer is specifically made in a way to utilize the characteristics of a coil, an inductor. That is to "focus" the magnetic flux. The flux is already focused in the area inside the coil. So I mean amperes law is all good, but an inductor is not a straight wire conductor. They behave differently, and engineered on purpose to take advantage of the properties of the inductor/coil. Thanks.
