Reactors at a Glance

Harmonic Filter Reactors

The power factor correction or capacitance of the power capacitor could form a unwanted resonant circuit in conjunction with the feeding transformer. Experience shows that the self-resonant frequency of this circuit is typically between 250 and 500 Hz, i.e. in the 5th and 7th harmonics region. Connecting capacitors can avoid these resonance phenomena in series with filter reactors in the PFC system. These so-called “detuned” PFC systems are scaled in a way that the self-resonant frequency is below the lowest line harmonic.


Application

  • Avoidance of resonance conditions
  • Tuned and detuned harmonic filters
  • Reduction of harmonic distortion (network clearing)
  • Reduction of power losses

Features

  • High harmonic loading capability
  • Very low losses
  • High linearity to avoid choke tilt
  • Low noise
  • Convenient mounting
  • Long expected lifetime
  • Temperature protection (NC contact)

Discharge Reactors

Discharge reactors are used in applications where discharging resistors are not discharging the capacitors fast enough. Fast discharging allows a fast re-switching in automatic PFC equipment. One discharge module is usually used per capacitor branch.


Application

  • Power factor correction branches

Features

  • Voltage: 230 … 690 V
  • Discharge time  230 V:
    • up to 25 kvar <10 s
    • up to 50 kvar <20 s
    • up to 100 kvar <40 s
  • 400 ... 525 V:
    • up to 25 kvar <5 s
    • up to 50 kvar <10 s
    • up to 100 kvar <20 s
  • 525 ... 690 V:
    • up to 25 kvar <3 s
    • up to 50 kvar <6 s
    • up to 100 kvar <12 s
    • to 100 kvar <12 s
  • Power loss PLOSS < 1.6 W

Customer benefits

  • Low losses
  • Fast discharging allows a fast re-switching in automatic PFC equipment
