It's well known that in high voltage transformers, the contents of harmonics in the applied voltage are induced by the non-linear behavior in the saturated part of the magnetizing curve of the testing transformer core. In addition, non-sinusoidal magnetization current causes a distortion of the secondary voltage. Is there any solution in order to improve the applied voltage signal and decrease its harmonic components ?
Hi Youcef
I suggest to use a low frequency filter (LC circuit) with high voltage inductance and capacitor which could help you to eliminate odd harmonic components.
Good luck

Thank you all. Mr Desai
Mr Desai, I've been looking for how to reduce working flux density and I've found this: https://www.researchgate.net/post/How_to_reduce_the_vibration_of_a_transformer
Thank you again
The waveform distortion of the emf at the primary side is caused by some series components (capacitor and inductor), when the transformer work at no load or lightly loaded, or when it is connected to a nonlinear load. the solution is to use harmonic mitigation technics.
this can help you:

Thank you Abdelmalik for your answer.
I would like to know if such techniques could be feasible for high voltage application? or there will be other considerations in this case ?
