Chapter 11: Problem 31
The three pieces of computer equipment described below are installed as part of a computation center. Each piece of equipment is a balanced three-phase load rated at \(208 \mathrm{V}\). Calculate (a) the magnitude of the line current supplying these three devices and (b) the power factor of the combined load. Hard Drive: \(5.742 \mathrm{kW}\) at 0.82 pf lag CD/DVD drive: \(18.566 \mathrm{kVA}\) at 0.93 pf lag CPU: line current \(81.6 \mathrm{A}, 11.623 \mathrm{kVAR}\)
