6-35 kV Oil-immersed, stepless adjustable arc suppression reactors (Peterson coils), РЗДПОМ type

6-35 kV Oil-immersed, stepless adjustable arc suppression reactors (Peterson coils), РЗДПОМ type

РЗДПОМ is oil-immersed, grounding, arc suppression reactors on voltage class 6, 10, 27.5, 35 kV with smooth inductivity adjustment. The control is accomplished by a smooth change of the non-magnetic gap between of the movable rod discs. On request, they can be equipped with automatic control. The rated power range of reactors 120 to 1650kVAr, with 100V voltage signal wiring.

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.
