  • Avoids resonance between the inductance of the supply transformer and the capacity of the capactiro bank
  • Eliminates over voltage and over current in the transformer and the capacitor bank
  • Protects capacitors against harmonics, avoiding premature breakdown of the capacitor bank
  • Limits the connection spikes of the capacitor bank, extending its lifetime and reducing microcuts in the voltage
