A Three-Phase, Three-Wire Circuit Delivers 175 Amperes at a Voltage

Question 10

Short Answer

A three-phase, three-wire circuit delivers 175 amperes at a voltage of 220 volts with a 0.85 power factor. What is the kilowatt load to the nearer hundredth?
k W load =3(E)(D)(PF)1,000 where k W load = 3-phase power in kilowattsi = current in amperesX = voltage involtsP F = power factor\begin{array}{llcc}\text {k W load }= \frac { \sqrt { 3 } ( E ) ( D ) ( P F ) } { 1,000 } &\text { where k W load = 3-phase power in kilowatts}\\&\text {i = current in amperes}\\&\text {X = voltage involts}\\&\text {P F = power factor}\\\end{array}
