Magnetic coupling enables the transfer of power from primary winding to secondary. The induced voltage at the secondary is a function of d/dt of flux. For low frequencies, where dt is high, he flux required will be high. To achieve such high flux, a high permeabilty ( ewuivalent to conductance in electric circuit) magnetic path is required. By putting what we achieve is this only. By wood, the permeabilty comes down to 1/5000

Meaning of cruciform core fro transformer?
A cruciform core in a transformer refers to a core structure shaped like a cross (or "cruciform"), which enhances the magnetic coupling between the windings. This design improves efficiency by reducing magnetic losses and allows for a more compact configuration. The geometry helps in achieving better performance by minimizing the air gap and optimizing the magnetic flux path, which ultimately leads to improved power handling capabilities.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
How do you design the transformer?
You can construct a transformer, and it's not particularly difficult if you know what you are doing. It's not possible to give you detailed instructions without knowing what type of transformer you need, and the answer to that depends on what it's for. A transformer consists of two coils of wire, electrically insulated from each other but magnetically coupled. How the coupling is done depends mostly on the frequency of operation. For electric power ( 50 or 60 Hz ) the coupling must be very tight, so the coils are wound onto an iron core. For audio frequencies you would generally do the same, although a ferrite core is a possibility. For radio frequencies, the transformer would be wound on a ferrite core if you need tight coupling for power transfer. Otherwise it might be wound without a core (usually referred to as an air-cored transformer). Please repost the question, saying what the transformer is intended to do.
What is the purpose of transformer core?
yes core is usefull in transformer since it it increase the permeability for the flux (i..e,it offers less relucyance path thanj air ).Their by decresing the losses in the transformer.
What was the invention of Nikola Tesla?
Tesla coil. An air -core transformer
What is air gap in case of transformer?
An air gap in a transformer refers to the intentional separation between the magnetic core and the windings, or between different parts of the core itself. This gap is used to reduce magnetic losses, control magnetic flux, and improve the transformer's performance under varying load conditions. It can also help prevent saturation of the core material, thereby enhancing efficiency and stability in operation. The size of the air gap is carefully designed to optimize the transformer's characteristics.
The coefficient of coupling between two air core coils depends on?
The coefficient of coupling between two air core coils depends on factors such as the physical distance between the coils, the number of turns in each coil, and the alignment of the coils relative to each other. It also depends on the relative orientation of the magnetic fields generated by each coil.
Why is a core type transformer mostly used in three phase inverters?
A dry type using air to cool instead of oil.
Name of transformer oil?
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
What is air blast type transformer?
An air blast type transformer is a type of electrical transformer that uses air as the cooling medium and insulator. This design employs a system of air blasts to enhance the cooling process by directing air over the transformer windings and core, thus maintaining optimal operational temperatures. Air blast transformers are typically used in high-voltage applications and are known for their efficiency and reliability in dissipating heat. They are particularly useful in outdoor installations where traditional liquid insulation methods may not be practical.
What kind of device is a telsa coil?
Tesla coil is a resonant air core transformer. There are other known devices that are like the Tesla coil.
What the transformer oil transformer provides?
Significantly-better cooling and insulation than air. This means that the transformer can operate at higher power ratings than an equivalent air-cooled transformer, and its internal electrical components can be much closer together, giving an oil transformer a much smaller footprint so it takes up far less space in a substation.
