In this paper, we consider a circuit for which the necessary equations are calculated and the optimal values of the mutual induction of the coils are found, at which the maximum energy transfer is observed. The results of this work allow us to conclude that the method of contactless energy transfer based on tuning the frequency is possible.

We consider the design of a three-phase two-winding power oil transformer with load regulation, with a capacity of 4000 kVA. Calculations of high and low voltage windings, distribution windings, shortcircuit voltage and no-load currents were made. Calculations of geometric parameters and finding the mass of the magnetic system of the transformer are ...
