FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and can be used in devices for self-regulating balancing of currents and voltages for a three-phase electrical network when an unbalanced three-phase load with varying power is connected to it. The substance of the invention lies in the fact that each core of the device is installed in the corresponding coil with the possibility of its axial movement and is additionally equipped with a spring located in the lower part of the base - under the core and has the ability to interact with it. Together, the device allows you to reduce the asymmetry of currents and voltages in a three-phase network with a neutral wire due to self-regulation of the inductance when the zero sequence current changes.
EFFECT: reducing the asymmetry of currents and voltages in a three-phase network with a neutral wire due to self-regulation of inductance when the zero sequence current changes.
