Why Is Leakage Flux Represented by an Inductor in Transformer Models?

AI Thread Summary
Leakage flux in transformers is represented by an inductor because it reflects the portion of magnetic flux from the primary winding that does not couple to the secondary winding. When the secondary winding is absent or disconnected, the transformer behaves like an inductor. This representation is practical since the leakage inductance is typically large, leading manufacturers to suggest a transformer configuration for efficiency. Additionally, using a one-to-one transformer provides isolation, enhancing safety and performance. Understanding these concepts is crucial for grasping transformer operation and design.

Hey, I am currently reading about transformers and one aspect of the equivalent circuit that I do not understand is why the leakage flux is represented by an inductor? Any help on this would be much appreciated.

Thanks!

Leakage flux is just the portion of the flux generated by the primary winding that does not couple to the secondary winding of a transformer. Without the secondary winding (or if the secondary winding is not connected) a transformer is just an inductor.
 
I just need a inductor,but the its value is large,so the manufacturer suggest to make a transformer style instead.So the theory told above is right.Thanks!
 
Why we use a one-to-one transformar
 
Isolation.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

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?

Thread 'What happens if shielded cable has a short to the shield?'

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...

Thread 'Why does the amperage go real high if there is a low voltage short?'

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...
