Zero Sequence impedance 1

[IAEA]

I am realizing a "Short circuit" analysis in an electric circuit with alternative current and I'd like to know bibliography where I can look for something about "zero sequence impedance".
Thank you in advance

Try the Schaum's Outline Series title "Electric Power Engineering" for a relatively easy treatment.

A zero-sequence current is a current that flows in the neutral when the three phases are not equally loaded, such as during a single- or two-phase fault.

It is an admirable undertaking to try to understand this subject, even for electrical engineers. Good luck!

To understand the zero sequence (impedance, voltage and current) it is recommended to be familiar with the other sequence components.

Therefore, check in the Symmetrical Components category for additional details.

One of the best reference in this topic I founded in the is
1- “Analysis of Faulted Power Systems (IEEE Press Series on Power Engineering)’ by Paul Anderson.

2-“Circuit Analysis of A-C Power Systems. Volume I: Symmetrical and Related Components” General Electric Company, Seventh printing, 1961 by C Clarke.

For historical and details how this was developed find the IEEE paper by C. L. Fortescue;
3- “Method of Symmetrical Coordinates Applied to the Solution of Polyphase Networks” AIEE Transactions, Vol. 37, 1918, pp. 1027-1140.

Here are few sites that could have good info in this topic:

System earthing have a big effect on zero-sequence quantities.
A very good book on this subject is "A practical guide to short-circuit calculations" written by Conrad St.Pierre.
