PEREZ-GOMEZ, Cándido Arturo; MAXIMOV, Serguei; OLIVARES-GALVAN, Juan Carlos  y  ESCARELA-PEREZ, Rafael. Analytical formula of the mutual impedance of a partial core transformer with conductive tapes. Ing. invest. y tecnol. [online]. 2023, vol.24, n.3.  Epub 17-Nov-2023. ISSN 2594-0732.  https://doi.org/10.22201/fi.25940732e.2023.24.3.017.

The present work shows a first approximation of the analytical model of the mutual impedance of a transformer with a partial cylindrical core considering the effective tensor values of magnetic permeability and electrical conductivity. This first model is based on the use of constant values to represent the effective relative permeability of the core material of this transformer. The analytical expressions obtained allow modeling the mutual impedance values for the following cases: filamentary conductor, conductors with a rectangular cross-section and for a two-coil device.
