Air-Core Reactors (ACR) provide a linear response of impedance versus current which is essential for numerous applications. The dry type design is maintenance free and environmentally friendly.
There’s a range of air core reactors to cater for various market segments such as power generation, T&D networks, industrial facilities, OEMs and electrical test laboratories.
For both industrial environments and networks, a broad range of cost-effective solutions:
limit the fault currents to levels compatible with existing protection/control equipment and as a result provide for a very cost-effective solution.
are connected between the neutral of a power system and earth to limit the line-to-earth current to a desired value under system earth fault conditions.
reduce the harmonic currents and transient overcurrents (ripple) in DC systems.
Harmonic filter reactors
are 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.
compensate for the capacitive currents of long transmission lines or cables, allowing more active energy to pass through the system.
limit the inrush and outrush currents of capacitor banks.
are used in the bypass/ discharge circuit in series compensation systems to limit the capacitor discharge current.
Arc-furnace series reactors
provide the necessary power factor correction and limit the unstable arc-furnace current and voltage.
Power flow control reactors
control the current into two or more parallel circuits.
Motor starting reactors
are connected in series with a motor to limit the inrush current during the motor starting operation.
test lab reactors are special ACRs used in test laboratories, mainly for current-limiting purposes. Other devices include duplex current-limiting reactors, split-phase shunt or zero tolerance reactors, etc.
