The manufacturing process of power transformers is complex because they are machines with a large capacity. Problems in calculating the parameters can cause unexpected failures and endanger the rest of the electrical system. For this reason, the transformer design parameters must meet the requested requirements. In this paper, the transformer's series impedance is calculated using the finite element method on three types of transformers: a single-phase column type power transformer, a three-phase armored-type distribution transformer, and a station service voltage transformer. The results are compared with those obtained through traditional formulations and those obtained experimentally by tests.
