RTFX

RTF FAMILY Three phase reactors for capacitor banks

RTFX

Anti-flash varnish finish, offering:

  • Protection against corrosive environments
  • Increase of electrical isolation
  • High compression capacity
  • Reduction of noise level
  • Increase of product's lifespan

​Safety class I

Includes thermal protection against overtemperatures

Possibility of tailor-made manufacturing

Technical remarks about the use of detuned reactors:

  • They avoid resonance between the feeding transformer's inductance and the capacitance of capacitors' bank
  • They eliminate overvoltages and overcurrents either from the transformer and from the capacitors' bank
  • They protect capacitors against harmonics avoiding early aging
  • They limit conection peaks of the capacitors' bank increasing their lifespan and reducing microcuts in the fedding voltage
  • RTFX inductances are designed to protect in front of harmonics capacitor banks power factor correctors.
  • The inductances tuned to 189Hz are the most common

Available accessories:

  • PT100 probe.
  • PTC probe
  • Different terminals
