transformers and tap coefficients

Dear Matpower community, My question is about tap coefficients. It is said in the data description that branch includes transformer if r=x=0. But actually in cases r and b =0. Is it misprint in data description or should I consider given values for x as b. Best, Vladimir

Yes, it is a typo. It should be r =b =0. Shri > On Aug 26, 2015, at 6:47 AM, "Vladimir Frolov" > wrote: > > Dear Matpower community, > > My question is about tap coefficients. It is said in the data description > that branch includes transformer if r=x=0. But actually in cases r and b =0. >
