The purpose of the reactors is to reduce possible short-circuit currents. The reactors can be connected to the grid along or across. In longitudinal switching, the reactors reduce the power flow and limit the short-circuit currents.
Shunt reactors are inductive elements, that are typically connected to transmission network nodes to compensate excess reactive power generated in ultra-high voltage overhead lines. They can also be plugged in to electricity network on the medium voltage side of the substation transformers. Shunt reactors are the simplest and cheapest way to compensate excess reactive power at low system loads.
We offer F- or H-class VPI, dry and oil reactors for indoor and outdoor conditions up to 5000 A / 52 kV.
