FIELD: electricity.
SUBSTANCE: invention is used in the field of electric engineering and power engineering. The method lies in the following: when higher harmonics occur from the side of studied non-linear load capacitive resistance is installed at step-down transformer output, and parameters of the above resistance are selected on condition of reduction of load voltage unharmonicity.
EFFECT: reducing voltage non-sinusoidality ratio and reduced impact of higher harmonics when variable non-linear load is available.
