Detuned Reactors

Detuned reactors are specific three phase inductors dedicated to attenuating the amplification of harmonics on highly polluted networks and to protecting the different components of the installation. They form a complete product range from 6 to 100 kvar and are available in the most common tunings like 135, 190 and 215 Hz for network voltage of 400/415V 50Hz. They must be chosen according to the capacitors they are associated with.
