Transformer Calculation is program for calculating number of coils and wire thickness at transformer.
If you have some experience in assembling transformers, then this program is perfect for you.
If you don't know anything about assembling transformers, please don't use calculations from this program for building your own transformer!
Wrong calculation can do damage to your electric device attached to electric network, and IT CAN KILL YOU !!!
You can still use this program to determine how big EI core of transformer must be, if you plan to buy transformer. Note there are lots of transformers that are hybrids, so if you need transformer for amplifier buy right sized transformer. Hybrid transformer are ordinarily small and under high load it can overheat.

Current version can calculate values only for standard transformer core, that's "W" and "U" profile of core.
Note that working frequency of all calculations is 50 Hz (you can use it for 60 Hz too), in next release I'll add ability to change that frequency.
Toroid transformers (ring profile of core) and others aren't supported.
How I decide to write this program? Well it's simple, I work calculation for new transformer and I didn't have that thin wire for coil. So I lose some hours while recalculating new voltage and amperage for wire which I have.
I started to assemble wire on coil and realize that wire isn't long enough. Then I write this program and lose 3 minutes to make new calculation for that transformer with new wire.
Transformer is finish and work perfect in my amplifier 2x7 Watts. :)

I think that you can find this program useful.
You can write to me suggestions, corrections and other things on e-mail: electronics(ατ) (replace (ατ) with @)

New program is stopped due lack of my free time. Thanks to all who wrote me e-mail and make suggestions for TODO list.

If you have knowledge, will and free time to create formulas which includes something from TODO list, you are welcome to join me. Currently I have constructed skeleton for new program and I only need formulas to integrate it.
Formulas used in this version are simplified with more tolerance values to accommodate different values used and it's not intend for precision calculation. Therefore listed changes require new set of formulas which are more complex and very precise.
So if you want to join into this project, e-mail me and you have your name in program.
However I'm open for commercial suggestions too, so if you have working and tested formulas I have time to make program.

Here is the list what else I can put in program :

Use this program with care!
If you already test and assemble transformer then that program may be very useful.
Otherwise do not try to assemble transformer using calculations from this program!
