| The Current Transformer
|
https://www.electronics-tutorials.ws/transformer/current-transformer.html
|
A helpful blog post detailing some of the underlying theory and equations used in making current transformers. It may be wise to use this as a baseline reference - but equations should be verified & cited from an EMAG or power electronics book.

Another blog-like post about general current transformers. One of the most useful things to get from this work is the phasor analysis of a current transformer.

This is a stack exchange post about making current transformers. Some pretty good breakdowns in the responses. Once again all of the work should be verified against a reputable source.

In this blog post, he makes a watt meter, and most notably winds the current transformer by hand. Something important to note is in his measurements he does not note any of the phase angle compensation - which is something I will have to characterize for my current transformers.

Another Stack exchange post about making CTs. Good listing of mathematics & variables used in designing CT.

| A Current Transformer Model Based on the Jiles–Atherton Theory of Ferromagnetic Hysteresis

Looks like a fancy way to model CTs mathematically. Likely an unnecessarily high level for this project. Don't think simulation will be necessary.

| An Efficient Compensation Algorithm for Current Transformer Saturation Effects
|
https://ieeexplore.ieee.org/abstract/document/1339324
|
This looks like a pretty good paper that details recognizing CT saturation and methods to compensate. Though I won't be looking at the specific algorithms in this paper - recognizing the saturation point may be an important point for device characterization.

They go into analysis about air gap transformers --- something that may be pretty transferable to the kind of analysis that I'll do for my transformers.

Analysis of CTs in distortion -- may be a good to set of tests to put our transformers under to characterize their robustness.

This website doesn't work very well - might be sketchy. But also a design handbook would be helpful
