Abstract| A diversity of formulas is given in literature for leakage inductance calculation
of transformers with interleaving of windings. In the paper, the meaning of included terms and
details of the application for concentric and pie windings transformers shall be discussed. Consid-
ering the limitation of common formulas to magnetically symmetric transformers an alternative
approach shall be demonstrated, which enables leakage inductance prediction also in the case of
transformers with magnetically asymmetric arrangements of windings.
