Power Factor Improvement Principle and Correction Methods

Low power factor is mainly due to the inductive loads. In industries, mostly inductive loads are used like induction motors, lamps etc.for various purposes. These inductive loads take lagging current and hence results in low power factor. Low power factor has many disadvantages. Therefore, power factor improvement is necessary to get rid of problems associated … Read more Power Factor Improvement Principle and Correction Methods

Poor Power Factor – Effects and Disadvantage

Effect of Poor Power Factor: The major effect of poor power factor is higher value of line current. We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. … Read more Poor Power Factor – Effects and Disadvantage

What is Power Factor? – Definition and Formula

Power factor is an important parameter for the calculation of active and reactive power in electrical circuit. It has significance only for AC circuit. For DC circuit, it is not considered for power calculation.Its value is unity for DC circuit and may vary in between zero to one for AC circuit. We know that power … Read more What is Power Factor? – Definition and Formula

Why does Induction Motor has Poor Power Factor at No Load

Induction Motor when started at no load has very poor power factor in the range of 0.1 to 0.3. For understanding the effect of loading on the power factor of Induction Motor, we will consider three components of current flowing in an Induction Motor namely Magnetizing Current, Stator Loss Component of Current and Load Component … Read more Why does Induction Motor has Poor Power Factor at No Load
