Harmonic Analysis of Non-sinusoidal Currents During Heating of Transformers
The results of the analysis of currents in the transformer windings when heated by low-frequency short-circuit currents are presented, for the description of which the Fourier series expansion of piecewise exponential functions is used. This makes it possible to mathematically model the heating process and solve the issues of the ratio of the power released in the electric and magnetic circuits of the transformer.
