Detuned Reactor Manufacturer in India

Detuned Reactor are used, in supply networks having a high level of harmonic distortion, when the final objective is reactive power compensation at the fundamental frequency. Their purpose is to avoid the harmonic currents overload to the capacitors by diverting them to the mains. Protection filters are made by connecting reactors in series with capacitors, in such a way that the tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonics, which is usually the 5th order harmonic. In this the filter has a high inductive impedance for all the harmonic frequencies.

By using these types of detuned reactors it is possible to avoid the following negative effects on the system:

  • Over-current during switching on the capacitor banks
  • Incidental resonance of Capacitors along with stray inductance
  • Overload of capacitor banks due to the harmonic resonance
  • Short lifetime of capacitors
  • Unintended triggering of the protective devices
  • Distortion of utility voltage waveforms and problems on voltage sensitive devices
  • Overheating of the utility transmission cables.Overheating of the Distribution Transformer
