Losses of active power of single phase transformers and reactors and twisted magnetic circuits

Features of active power losses calculation and optimization of transformers and reactors by the criterion of a minimum of losses on the basis of an objective functions with dimensionless indices of a technical level and invariant relative controlled variables method are shown. The effect on the loss of active power of the replacement of rectangular forming contours of rods and winding coils on hexahedral in variants of planar and radial three-rod static electromagnetic systems with twisted magnetic circuits at frequencies of 50 Hz and 400 Hz is determined.
