You own a factory that uses several conveyor belts and other motor-driven machineries. Upon measuring the factory's apparent power requirement and power factor, it turns out that it runs at 15 MVA at 0.7 lagging of; therefore, it is too inductive! To avoid electrical code violations, the factory must operate at a pf of at least 0.9 lagging.
