Maxwell, circuit theory, etc. I'd thought the analogies were good enough to understand. All they really did was confuse me. Learning the theory was what began to set me straight.

When I was first learning about electricity, I was given more analogies about what it's "like" than any reasonable person could reconcile to the actual phenomena. I've heard all of the references mentioned in the OP and came away more confused than I'd arrived after having heard each. It was...

You should be able to plug and chug, but I'm not able to use a program to give me a quick and dirty answer, and I don't have time to do the calculation by hand. See if this can shed any light onto your problem...

Ah, yes... I should have differentiated between Load inrush and Transformer inrush. Any transient or fault type current flow "outside" the transformer will simply propagate through the machine since, as the OP has pointed out, the transformer is a "stupid" machine. To further illuminate the...

Jim Hardy always has the best of explanations. They're always understandable to us more simple-minded and less experienced. He and anorlunda are the "power-houses" when it comes to anything power related on this forum. I have found their insights vastly useful. I have some questions about the...

Theoretically, there will be no inrush at all if the transformer is already loaded since it is a phenomenon experienced only at startup. In reality there may be some slight inrush current associated with extreme load fluctuations but not enough to elicit any consideration. Yes, but I don't see...

The idea of Inrush current is that the flux within the core of the transformer cannot change instantaneously. If you remember your ideal relations, the flux will be at its negative maximum when the input voltage is zero; obviously, this cannot be the case in reality. This means that the flux...

Just as pertinent and beautifully written as the others. Thank you for sharing your knowledge.:smile:

This corroborates my thoughts. There doesn't, at first glance, seem to be enough economic "skin in the game" to get all excited and change an entire paradigm of thought. HIF are a problem, but not one that occurs frequently enough and in a manner damaging enough to worry too much about. The...

I have more of a discussion type question than one about Electrical Concepts (though I suppose it will devolve into that area). I've been doing a bit of reading about settingless relaying schemes and was wondering how they really improve over the traditional methods? The method of Dynamic State...

Welcome. This is good stuff! It took me a while to figure out not all search engines return the same information. It's a good thing to know. Good luck and take care.

Computer Vision and Super Resolution. Those two areas are rife with room for improvement as well as being highly theoretical both in experimentation and practise. Good luck :)

The page was unavailable and the link was one of the first things I found in a Google search. I saw him Monday evening and explained in more detail as best I could. I don't know that I did justice to the topic, but whatever I said seemed to have cleared whatever confusion he was having. I'm...

My Father's friend repairs electric motors and, occasionally, he comes to me with questions that require more of an "engineering knowledge." He asked me this past Sunday if I could explain to him what are Chord and Chording Factor, and, as has happened to me before, I felt I had a pretty good...

As an aside, you should know that, in this case, "couldn't" is the right word to use. There's a significant difference between the two phrases and, unless you want to come across as unschooled, you should try not to confuse them. ;)
