Problem 4- A large 3-phase industrial load draws 3.6 MVA at 0.85 power factor lagging from through a three-
phase 12.47/7.2 kV 3-wire overhead distribution line. The phase conductor is #1 ACSR “Robin". Taking 3.6
MVA and 12.47 kV as base values, determine
(a) The base impedance in (N)
(b) The reactive power drawn by the load (p.u.)
(c) The total current (p.u.) drawn from the power supply
