Determine leading or lagging power factor
WebNov 15, 2014 · Linears also do "weird" things with the input current due to the action of the rectifiers and due to internal bulk capacitances. Again, not a pure phase-shift sort of situation. There are actually many definitions … WebJun 20, 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.
