Modeling of toroidal transformer

AI Thread Summary
Modeling a toroidal transformer with specific permeability and saturation flux density can be complex, especially when simulating a split core toroid clipped onto a power line. While some suggest that the calculations can be performed simply by hand, others emphasize the need for software that can handle various materials and geometries, as well as assess coupling at different frequencies in the kHz range. The discussion highlights the importance of considering different materials like nanochrystalline, amorphous, and electrical steel to achieve accurate modeling. Users are seeking recommendations for software packages that can accommodate these detailed requirements. Overall, the conversation underscores the balance between simplicity and the need for precision in transformer modeling.

I want to model a toroidal transformer with a given permeability and saturation flux density. Specifically, I want to model a split core toroid clipped onto a power line, to simulate coupling, so it is really a one turn secondary and a primary of arbitrary turns.

Any software packages out there that are able to do this?

There are magnetic design packages, but why bother? This is so simple, you can do it on a 4x6 index card in a few minutes. It's little more than an Amprobe (tm). Is there some detail that you specifically want to see?
 
I'm looking at using different types of material (e.g., nanochrystalline, amorphous, electrical steel) with different geometries and air gaps. I also want to assess the coupling at different frequencies (in the kHz range), so it becomes a more involved problem than just working out the inductance of a toroid.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
