    Harmonic Filter Calculation

    Which order harmonic would be effectively removed from a power system by applying a single-tuned filter with a 0.55 μF capacitor and a 500 mH inductor?

    How do you calculate this?

    I believe the formula is 1/(2PI*SQRT(LC))

    Can you walk us through this calculation? I have tried doing it several times and haven't come up with what they say is the correct answer yet.

    L*C =0.5*0.00000055=0.000000275
    sqrt(0.000000275)=0.0005244
    2pi*0.0005244=0.003294
    1/0.003294=303.49hz
    303.5hz/60hz=5.058 or 5th Harmonic
