POLYLUX’S RTF SERIES

Three phase reactors for capacitor banks

The RTFX series is made up of three-phase rejection inductances for capacitor batteries with ratings between 4.4kvar and 88.8kvar.

These reactors are used to protect the batteries of power factor correcting capacitors against harmonics.

Some of its utilities:

  • They prevent resonances between the power transformer inductance and the capacitance of the capacitor battery.
  • They eliminate surge currents and overvoltage in the transformer and in the capacitor battery.
  • They protect the condensers against harmonics, preventing their premature ageing.
  • They limit the capacitor battery connection peaks, thus increasing their life service life and reducing micro power cuts in the supply voltage.

The reactors of this series can be manufactured with different filter factors:

  • P = 5.67% (RTF5X, capacitor voltage 440V to 50Hz and resonance frequency 210Hz)
  • P = 14% (RTF14X, voltage 460V to 50Hz and resonance frequency 135Hz)

Both factors cover from 5kVar to 100kVar power range.
