Article 4.6.2K : What is Leading and Lagging power factor?
Lagging and Leading power factor When the current ‘I’ lags the voltage ‘V’ by an angle ‘θ’ is said to be as ‘Lagging power factor’ When the current ‘I’ leads the voltage ‘V’ by an angle ‘θ’ is said to be as ‘Leading power factor’. The figure which ...
Performance Assessment of Power Factor Capacitors.
Voltage effects: Ideally capacitor voltage rating is to match the supply voltage. If the supply voltage is lower, the reactive kVAr produced will be the ratio V1 2 /V2 2 where V1 is the actual supply voltage, V2 is the rated voltage. On the other ...
Disadvantages of low power factor.
In case of Low Power Factor, Current will be increased, and this high current will cause to the following disadvantages. 1. Large Line loss. 2. Large KVA rating and size of Electrical Equipments 3. Greater Conductor Size and cost. 4. Poor voltage ...
Comparison Between Leading and Lagging Power Factor in iPFC.
Comparison Chart Basis for Comparison Leading Power Factor Lagging Power Factor Basic The load current leads the supply voltage by certain phase angle. There is a phase difference between voltage and current where load current lags the supply ...
Article 2.0.4D : What is the purpose of Power Assist?
Power Assist can be installed between Meter & Gateway to avoid "240V AMF input". Existing method (before Power Assist) - "240V AMF" input needs to be connected to the meter to detect the power as DG. New method (After Power Assist) - When power ...
