FIELD: electricity.
SUBSTANCE: invention refers to the sphere of electrical engineering and is of relevance for design and development of technical equipment ensuring improved quality of electric power transmission through three phase four-wire electrical networks and reduction of power losses related thereto due to anharmonicity and asymmetry minimisation. The desired effect is due to the electromagnetic compensator identifying among the phase currents the one whose frequency value is equal to 150 Hz current which current is immediately injected in phase opposition to the third harmonic of the neutral lead current.
EFFECT: compensation for the largest spectral harmonic as circulating within the currents neutral lead.
