Web20 jun. 2013 · 2. Leading power factor means that the current leads the voltage, that is, the load is capacitive. If the load is inductive then the power factor is lagging and its sign is positive. When calculating kW from kVA use absolute value of the power factor because it will be the same whether the PF is leading or lagging. Share.
