Hello!

Who knows about 3d models of transformers and el. substations including equations and theory?

Also it is enough to use usual Kirhgof laws and others to create a tr-r?

Here’s a 3D model:

And here’s the theory:

Kirchhoff and phasors are more than enough. Note that symbols with primes are referred to the primary side

Thanks! And if we create substations - which consist tr-r and switches,and others?

Pretty sure ABB has step models of medium voltage switchgear publicly available. Probably others, too.

BTW: I would strongly advise against building substations based on Internet forum knowledge.

What is ABB? )) Thanks

ABB is a manufacturer who makes transformers that do not fit on a PCB such as:

ABB’s Idea of a substation is possibly also slightly different from what you have in mind:

Let me know if you render it with KiCad 3D-Viewer

I’ll let you know if the viewer can’t handle it.

Thanks. Suppose we have a method, that can calculate parameters and equations of el. circuit. In arbitrary type of equations, and interval - what can we add here so the system can solve problems of radio circuits - and be like a candy? &)

Hi!

Who can help with substations formulas - examples of simple with transformers?

Any papers in pdf. Scientific engineering
