Power Factor What is Power Factor ? It is the ratio of the active power of the fundamental wave the apparent power of the fundamental waveform Cause: Inductive load which cause large difference of phase angle between current and voltage,Varying load, industrial heating furnace, harmonic currents, electrical discharge lamp, AC motor, arc welder, furnaces, fluorescent lighting and air conditioning. Effect: overheating of motor and poor lightening. Power factor correction: This is normally achieved by the addition of capacitors to the electrical network which compensate the active power. To reduce losses in the distribution system, and to reduce the clectricity bill, power factor correction, usually in the form of capacitors, is added to neutralize as ch of the magnetizing current as possible. Capacitor included leads the voltage, producing a leading power factor. The corrected power factor will be 0.92 to 0.95. Why to improv...
