MRA reactor are three-phase:
MRA reactors are filter for harmonic, used to prevent resonance occurring , which are extremely dangerousness situations for the electric system because of ensuing overcurrents and overvoltages.The reactor are used with the sole purpose of correcting the power factor of the loads generating harmonics.
The most commonly used tuning frequencies are:
210 Hz corresponding XL = 5.7% XC
189 Hz corresponding XL = 7% XC
134 Hz corresponding XL = 14% XC
Installation: Indoor or Outdoor
