Reactors for high-voltage networks are power devices designed to regulate reactive power, stabilize voltage, and limit currents in power transmission lines. They ensure the reliable operation of high-voltage substations, compensate for excess inductance or capacitance in the grid, and prevent overloads during both normal and emergency conditions.

Reactors are installed in networks of various voltage classes and perform key functions:

voltage stabilization during load changes;

limiting short-circuit currents;

compensating for reactive power;

improving the stability and reliability of the power system.

Purpose of Reactors

Shunt reactors—for compensating capacitive currents in long power transmission lines.

Series reactors—for limiting short-circuit currents and regulating power flow.

Filter reactors—for use in high-frequency filter circuits and reducing harmonics.

Starting reactors—for limiting the starting currents of large motors.
