hello sir, In case.m file ratio is considered as ratio of vf(from bus voltage) to vt(to bus voltage)if a transformer is connnected between the two buses.
in case57.m file , between bus 39 ( vf=0.983KV) and bus 57 (vt=0.965KV) a
transformer is connected.
the obtained ratio is vf/vt=1.0186.
but in the file it is written as 0.981 which does not match with the obtained
ratio.
so which ratio is correct?
thanks in advance
regards
