POWER FACTOR #CAUSES OF LOW POWER FACTOR Induction Motor is the most commonly used A.C. motor.it is used for a variety of variety of purposes at full load a 3-phase induction motor operates at a power factor of around 0.8 lagging. At part loads, the power factor is still poorer. the power factor is still poorer. the power factor of single-phase induction motors is about 0.6 lagging Causes of low Power Factor . The main cause of low Power factor is Inductive Load. As in pure inductive circuit, Current lags 90° from Voltage, this large difference of phase angle between current and voltage causes zero power factor . The transformer drow a magnetizing current from the system .this current is at a power factor of zero lagging. Miscellaneous equipment like are lamps, welding equipment etc. also contribute to low power factor in the system # EFFECT OF LOW POWER FACTOR To meet the load requirement at a low p...
