A link between EMTP-RV and FLUX3D for transformer energization studies

This paper presents a programmed link between the electromagnetic transients program EMTP-RV and the finite element field solver FLUX3D. The model created in FLUX3D is driven from simulation designs in EMTP-RV. The test cases presented in this paper demonstrate that the coupling method is numerically robust and with sufficient accuracy. This approach benefits from EMTP advantages in modeling large-scale networks and from field solver advantages for detailed representation of power transformer iron cores.
