Facilities and factories width a high proportion of variable speed motor drives and/or other harmonic generating loads may require a detuned capacitor system. This would perform the function of power factor improvement while preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the mains.

Therefore, we offer three phase filter reactors to be used in the capacitor banks.
Low-loss reactors are made of specially selected transformer sheets and manufactured with flat or round copper wire technology. They are dried and impregnated in a vacuum which ensures that they can withstand high voltages and offer a long operating life. Reactors can be supplied with aluminium windings on request. Depending on their rated power, the reactors are provided with either terminal blocks or lugs.
If the operating temperature of 120°C is exceeded, the reactor circuit is disconnected by a thermal switch.
