Not having recently referred to the 2001 edition, I am not sure of this particular table, but I do know that the latest version is not as insightful and helpful to new engineers. I was not impressed. It has removed many hand calculation procedures too. Anyone who has 1986 version, hang on to it. It will become another highly sought after edition.
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.
