Oil-immersed reactors are series reactors that are utilized in line series connections to limit the current, reducing fault currents to the level requirements. These reactors can be customized to accommodate your personal needs and are available in single phase or three-phase types. Plus, their construction can be acquired unshielded, non-magnetically shielded, or magnetically-shielded.
Many reliable series reactors have been manufactured by Alstom Grid, working to transmission lines so that throughput ratings reach up to 2000 MVAr or over.
One type of reactor are the earthing reactors. These types are the solution in prohibiting the increase in voltage, as well as short-circuit currents, as in the case a fault line occurs. It can also be used when a neutral point cannot be accessed in the transformer wherein an artificial neutral will likely be created. This consists of a winding in a form of zigzag that is connected between its reactor and a main transformer.
