Abstract :
A reported digital simulation of polyphase transformers uses a matrix of incremental inductance coefficients to model core non-linearities. An improvement in the form of a matrix transformation technique for evaluation of the coefficients for any type of core is described. A coil/branch incidence matrix and a magnetic loop transformation matrix for incremental fluxes are introduced.
