Category:
  • Detuned filters chokes/ reactors work in series with capacitors to divert /absorb the harmonic noise (major 5th of 50 =250 Hz but detuned to 189 Hz) to an extent of 20%.
    • Range KVAR to 500KW
    • Frequency: 50 / 60 Hz
    • No of phase: 3 phase
    • Resonance frequency
    • Voltage 380 to 480V AC
    • Detune factor: 5.6 to 14% of voltage
    • Peak current & linearity: 173%imes the rated fundamental rms current within 5%
    • Over load limit: can with stand 200% for 1 min
    • Thermal current: 110% of the rated
    • Inductance tolerance +or-3%
    • Operating ambient:-20 to +50C
