F6FLT That the magnetic energy of a transformer is constantly fed by the primary current and constantly consumed by the secondary current is nothing new. First we need to be clear that nothing is "consumed". Energy cannot be created or destroyed only transformed. Energy is transferred from the primary to the secondary by way of a changing magnetic field. I say "magnetic field" as a generalization but it should be understood the field is made of billions of smaller magnetic fields relating to the atoms which make up the conducting and magnetic material. The quasi-concomitance of the two gives the illusion that the transformer doesn't store the energy passed from one to the other, but this is not true. There is a delay during which the energy is stored in magnetic form in the transformer core, during this very short transfer time. The principle is the same as if energy were passed through a capacitor alternately switched from input to output.
I would agree to some extent. I needed to know the actual facts of the matter so I started placing and embedding hall effect sensor arrays in and on inductors and transformers. As you say there is always a slight delay but I found there is much more to it. You see most don't seem to understand the how and why of the actual mechanism driving the energy transfer. In reality the secondary of a transformer acts almost identical to a shaded pole. That is, the primary current starts producing an expanding magnetic field which induces the secondary. The induced secondary then produces it's own current and secondary magnetic field. The secondary magnetic field then opposes the primary magnetic field which induced it in the first place. We can measure the extent of field opposition as a local increase in the magnetic field density and a shift in field polarity. So in fact the induction process looks more like this... Primary current, delay, primary magnetic field expanding, delay, secondary current induced, delay, secondary magnetic field expanding, delay, secondary field opposes the primary field, delay, increase of field density at primary/secondary transition point. Ergo, it is not one delay but many during each step of the induction process. I would also note my experiments were made on transformers having separate primary and secondary windings. If a primary is wound over the secondary or vice versa it is nearly impossible to track the field changes. AC
