How to use constants that apply to specific single- and 3-phase voltages to calculate current (I) and kilowatts (kW).

Cable let through power = [1,000 x (kV phase-phase) 2] ÷ [cable impedance (ohms) per phase, per 1,000 ft x total distance (ft)] = [1,000 x (12kV) 2] ÷ {0.15 ÷ 1,000 ft} x 100,000 ft = 9,600kVA let ...
