Abstract
Identification of Preisach model supposes a perfect experiment. One condition is that
prescribed harmonic current without any errors flows in the toroid primary winding. The
condition can be ensured by a suitable filter that was designed after the complete analysis of
sources of signal errors. The filter was analysed by the use of circuit theory and a very simple
experiment was realized for its measurement. Good agreement between experiment and
simulation was found and small deviations explained. The filter significantly reduces all the
errors in primary part of apparatus and improves the Preisach model simulation results.
