Subject Power System Quality Q23. The contract load of a dairy plant at 11 kV, 60 Hz is 800 kW, but the peak demand of plant recordedin last three years has not exceeded 600 kW at average power factor of 78%. As per local electricityregulating authorities' norms consumer must maintain a power factor of 93% to avoid non-compliancepower factor penalty. What will be capacitance (in micro farad) of a capacitor bank required to install tomeet the requirement?(a) 8.56(b) 7.13(c) 5.35(d) None of the optionQ24. A low pass passive filter has connected to 12 V, 1-kHz input signal. The filter is consists of 1.5 k2resistor and 0.15 µF capacitor. What will be the amplitude (in volts) of the output signal of filter?(а) 6.92(b) 8.48(c) 6.22(d) None of the optionQ25. A smelting unit consists of arc fumace is supplied by distribution system and has analyzed for theharmonics. It is observed that in equipment 1.5 Q resistive element is the path for a fundamental currentof 1.5 Amp containing additional 3rd, 5th and 7h harmonics level whose amplitude are inverselyproportional to their harmonic orders.
