    TRIPPING OF HARMONIC FILTER

    There are five capacitors in parallel in each phase with the following rating. 44 MFD/phase, 200 kVAR/unit, 5 kV/unit, five of them in parallel. The expected reactive per phase is 1,030 kVAR. The operating voltage of the capacitor is 3.81 kV per phase. The delivered reactive power is 632...

    TRIPPING OF HARMONIC FILTER

    For the given value of C = 220 MFD/phase and L = 1.92 mH, the calculated resonant frequency is 245 Hz. This is 4.9f for the 50 Hz system and 4.08f for the 60 Hz system. What is the voltage rating on the capacitor unit? What is the kVAR of the given unit? How are they connected (how many in...

    TRIPPING OF HARMONIC FILTER

    The tuned frequency of a harmonic filter is related to the kVAR of the capacitance and the reactor rating. In the case of the capacitance, the operting voltage and the rated voltage are different due to the design approach. Therefore, there is a possiblity that the filter tuned frequency is...
