I L 141.713A = I L S in 3 V L = Now we can solve for the line current using the three-phase power formula S in 117.818 kVA = S in P in F p = Since we know the power factor, we can find the apparent power: P in 107.214kW = converting to watts: P in 143.777hp = P in HP out η = HP out 134hp = HP out loading HP rated = First find the power out: Solution F p 0.91 = loading 67% = η 93.2% = HP rated
