Oil-Immersed Iron Core Shunt Reactors are designed to absorb excess reactive power and improve the voltage stability and energy efficiency of medium and high voltage power systems.
These reactors provide inductive compensation for the capacitive reactive power generated by long transmission lines and underground cable networks, increasing active power transfer capability while preventing overvoltages. They can be connected directly to transmission lines or to the tertiary winding of power and distribution transformers.
The reactor core is manufactured from high-grade ferromagnetic steel with one or more integrated air gaps. This air-gapped core design provides excellent mechanical strength and ensures reliable performance under both normal operating and fault conditions.
For high-voltage and high-power applications, Hilkar recommends integrating RC snubber filters to suppress switching transients and protect switching equipment from excessive overvoltages, improving overall system reliability.
In high-power and high-voltage systems, shunt reactors should be used with RC snubber filters. Because switching transient voltages are extremely high in these systems, they can damage switching devices without proper damping.
