It would be hard to find which branches in the MATPOWER data constitute a three-winding transformer if you don’t have the original cases. I guess you’ll just have to choose sets of three branches and assume they constitute three-winding transformers.

However, three winding transformers are modelled as three different branches. So, If I want to simulate the outage of such a transformer I must take three braches at a time. The problem consists on identifying the three winding transformers. How do I identify a three winding transformers within the mpc.branch matrix? I tried to do it by checking different baseKV in mpc.bus; however all baseKV values are the same. Has anyone had the same inquiry? Can anyone give me some hints? Best regards, Jesús López
