Air Core Reactors

Air-Core reactors provide a linear impedance with respect to current which is crucial in many applications where an iron core reactor would otherwise saturate.

Some typical applications include:

• Shunt Reactors – Compensate for the capacitive currents of long transmission lines or cables, allowing more active energy to pass through the system.
• Current Limiting Reactors – Limit the fault currents to levels compatible with existing protection/control equipment and as a result provide for a very cost-effective solution.
• Filtering Reactors – Usually connected with capacitors and resistors in filter circuits to reduce harmonic content in the network which cause higher losses, high neutral currents and interference with computer and telecommunications equipment and which are responsible for high harmonic distortion levels.
• Neutral Grounding Reactors – Connected between the neutral of a power system and ground to limit the line-to-ground current to a desired value under system ground fault conditions.
