摘要
FIELD: electrical engineering.;SUBSTANCE: inductance of a lower winding in three-phase three-winding power transformer or autotransformer is used as inductance in a serial string of the filter. Otherwise in order to attain the technical result the filtered frequency within range of these two frequencies is calculated by selection using equivalent circuit of high-voltage mains and capacity of the bank of capacitors is set under terms of resonance in series-resonant circuit at the calculated filtered frequency.;EFFECT: improvement of electric energy quality in the mains due to reduction of current and voltage unharmonicity.;2 cl, 3 dwg
