BUFF BOOK IEEE Std 242-2001 vs 1986 (Transformer Impedance Table)
(OP)
I can't seem to find the Impedance Data for three Phase Transformers in the IEEE 242-2001 Buff book.
It use to be on page 52 of the IEEE 242-1986 edition.
Did they remove it?

As for tranformer impedance data, go to Square D website, look up power transformers and will get many tables. I am sure other leading mfr websites will have too.

I have the book. Did you need the impedance for a particular size?

I do have both books, I am just interest and really curious on why did the IEEE remove a lot of the hand calculations and typical transformer impedances tables from the buff book? It seems that the 1986 is a lot more useful then the 2001 edition. That doesn't make sense to me, wouldn't a new edition just refine and improve the older edition? In this case, it looks worse.

This data is in Conrad St Pierre's book on Short Circuit Calculations.
