Methods for calculating the intrinsic and mutual leakage inductances based on the use of the vector potential of the magnetic field are considered, expressions are derived for the quantitative determination of the intrinsic and mutual inductances of the leakage fields, taking into account the geometric features of the coils, conductors and the relative position of the objects under study. The results obtained can be used to determine the parameters of the refined equivalent circuits of power transformers.
