FDUEG developed a great experience in manufacturing dry type iron core reactors. These devices can be installed in industrial environments, with special working conditions and load profiles. The following paragraphs list the main iron core reactor families produced by FDUEG.
They are used to compensate for capacitive currents in their network, stabilizing the voltage. They can sport wide regulations, to dynamically balance industrial loads in terms of reactive power.
Used when AC/DC converters are parallel connected, to balance the current in output of each rectifier. The side effect on the voltages improves the performance of the conversion stage.
As harmonic filters, they reduce the current harmonics present in AC grids. Usually coupled with capacitors, the resulting tuned circuits allows to control the high harmonic content generated by power electronic components. It is the most common category, having widespread usage with electrical equipment.
Placed before AC/DC converters, they are line impedances damping current harmonics and abrupt voltage variations in the power lines. If they are connected after the converter, they absorb the disturbances due to switching; the usage of such devices improves the performance of the converter, reducing its aging.
They reduce current ripples in DC systems. They are carefully designed for the specific harmonic component appearing on the DC waveform, in terms of frequency and amplitude: this precise setup greatly reduces the losses, improving the system’s performance.
They simulate the actual working conditions while testing a device. FDUEG designs them based on a client’s needs, to be used for tests as the ones on capacitors and mechanical switches, for current limitations, power factor correction or as artificial load. They can feature multiple combinations setups, wide regulations, special and sever duty cycles.
They allow to earth a system’s neutral, while limiting the short circuit currents towards ground. In tuned version, their coupling with the line’s capacitance eliminates a fault current.
They limit the inrush currents on induction motors while they start. Placed on the feeding line only when a motor needs to be started, they can reduce the currents to 2,5/3 times the rated. They are also available in air core version.
