Two Winding Transformer Equivalent Model of Three Winding Transformers for MATPOWER
MATPOWER is one of wide used authoriterative open source software of power flow calculation in the world. However, it only provides a model of the two-winding transformer thus limiting its application in power system with a three-winding transformer which is very popular in the power system.

Experimental studies on power transformer model winding provided with MOVs
Surge voltage distribution across a HV transformer winding due to appearance of very fast rise time (rise time of order 1 μs) transient voltages is highly non-uniform along the length of the winding for initial time instant of occurrence of surge.
