A 60-Hz three-phase line composed of one ACSR Bluejay conductor per phase has flat horizontal spacing of 11 m between adjacent conductors. Compare the inductive reactance in ohms per kilometer per phase of this line with that of a line using a two-conductor bundle of ACSR 26/7 conductors having the same total cross-sectional area of aluminum as the single-conductor line and 11-m spacing measured from the center of the bund les. The spacing between conductors in the bundle is 40 cm.
Design a digital notch filter of the form H(z) = (1+cz-1+dz-2)/ (1+az-1+bz-2), which has a notch at fo = 60 Hz and a 3-dB width of Δf = 20 Hz. The sampling frequency fs = 8 KHz. Determine a, b, c and d.
