Q6. The three-phase average power rating of a central processing unit (CPU) on a mainframe digital computer is 22,659 W. The three-phase line supplying the computer has a line voltage rating of 208 V (rms). The line current is 73.8 A (rms). The computer absorbs magnetizing VARS. (a) Calculate the total magnetizing reactive power absorbed by the CPU. (b) Calculate the power factor.
