The reactors are designed for compensation of the current capacitance component in single-phase grounding faults. The reactors are used to reduce an earth fault current, for decreasing of voltage recovery rate on the damaged phase after extinguishing the grounding arc, for surge reduction at the arc re-ignition and for creation a conditions for its spontaneous extinguishing.
