What is Power Factor? What is Leading & Lagging Power factor ? Power Factor Correction Methods

In this video, what is power factor, what is the significance/importance of power factor, what is leading and lagging power factor, and how to correct the poor power factor (power factor correction method), has been explained.
What is power factor:
Power factor is the ratio of True power to the Apparent Power.
It is also represented as the Cosine of the phase angle between the voltage and current. (cosφ)
True power: it is the power which is actually utilized for doing some useful work.
Reactive Power: It is the power which is used for generating the magnetic field in the inductive component of the load (e.g motors).
Apparent Power: This Apparent power is the total power which is being drawn from the mains. It is the vector sum of True and Reactive Power.
What is leading and lagging power factor?
Leading power factor: When the load is capacitive (Capacitive reactance is dominant) then current will lead the voltage, and the power factor is known as the leading power factor.
Lagging Power Factor: when the load is inductive, (Inductive reactance is dominant, then current will lag the voltage, and the power factor at that time is known as the lagging power factor.
The significance of power Factor:
When the power factor is less than 1, then the load is not purely resistive, and the power which is drawn from the mains is more than the actual power which is required for doing useful work. (e.g Running electrical fan)
So, this additional power is the burden on the power supplier, as they have to provide this additional amount of power and hence additional current, which they used to imply on the consumer in terms of penalty. And it is known as the power factor penalty.
Power factor correction:
When the load is linear and inductive, then by connecting the capacitor banks in parallel to the load, power factor can be improved.
What is displacement power factor?
For linear loads, the power factor is known as the displacement power factor.
What is distortion power factor?
When the load is non-linear (e.g Variable Frequency Drive), then it will generate harmonics of the current, and the current waveform will get distorted. So, this harmonics of the current causes the degradation in the power factor. So, this type of power factor is known as the distortion power factor. And it can be improved by connecting the passive or active harmonic filters.
This video will be helpful to all the students of science and engineering in understanding the concept of power factor in the electrical circuits and systems.

One thing I don't really get; in the video the circuit has a true power of 720 W and a reactive power of 720 VAR. When I look at the graphical display (@ 7:05) I only see a small portion of the power sine wave going negative. Can you explain/show me why the VAR amount is that large in numbers, but that small on the graphical display? Thank you in advance

Thank u sir.

[@vlogncm3957]

15:11 , you said that to we need that the value of Xl be equal to Xc so that they cancel each other out. But the circuit is in parallel to each other. So I guess that what you mean by cancel each other out is when we get their respective reactive power is that the plot of Q of L and Q of C will cancel each other? Am I right?

[@pior9988]

what if we have inductor and capacitor in the same load, it okay to put an additional capacitor parallel with them all ?

How can i reduce harmonics current

[@anivinderreddyboreddy3203]

Sir the phase will reduce if we add capacitor in series but why did u add that in parallel sir and xl xc both doesn't came equal???

[@krishnakhandelwal9466]

Amazing. Thank you so much. One question: Why was capacitor connected in parallel and not in series?

[@manoharp6800]

In series also we can connect but in parrlel it is more efficient..

[@amarnathmishra1461]

Capacitors in series are adopted for improving the voltage profile.

[@dwaram.rajani3594]

Thank you sir,if you explain this video in hindi

[@37prakhar]

Sir, at 7:30, you take P=I(max)^2 x R ; not I(rms)^2 x R, why?

[@ahmedalazazi2895]

Fantastic explanation Can you please tell me how do I know the PF in my house

[@blessoneasovarghese9834]

calculating power factor in a house using impedance and resistance is tiresome. If you know the phase angle between voltage and current , you can find p.f. easily by taking the cosine of that angle. That angle will be found out by the electricity meter installed at home

[@gachiismanly6412]

Sir I have a doubt in 16:11 why did you connect the capacitor in parallel and not in series? Please help me

[@darpangupta877]

Same doubt

[@bbgfxxftghjjjhbfdddddffg8139]

What is non Linear loads and how it distorts th power factor ?

[@ALLABOUTELECTRONICS]

Variable Frequency drives, servo drives, and bridge rectifier circuits are the example of nonlinear loads. This non- linear load generates the harmonics of the current. And these harmonics also draws additional reactive power. Hence, the overall power factor of the system reduces.

[@aryamehta007007]

4:29 why you have not included frequency of omega to calculate I ?

[@ALLABOUTELECTRONICS]

Here, the voltage source is 240 V, 50Hz. So, the value of XL ,which is j40 is for 50Hz. And here we are assuming that the voltage source frequency is not changing. So, that is why frequency is not included for the calculation of I. I hope it will clear your doubt.

[@StoryVerse261]

You must be an IIT OR MIT dropper

[@Concefacts]

Reactive power is nothing but the power oscillations in the circuit due to inductors and capacitors present. It is really confusing when we are studying reactive power only with the phasor diagram, I have explained the concept with the help of fundamental waveforms in my Chanel. Also explained why reactive power compensation is necessary, how we can compensate.

[@amp_001]

If we connect capacitor in series with R&L then can we take Xc=-j40 ohms

[@kusalthiwanka8630]

normally we do not use a capacitor in serial. capacitors connect parallel to the circuit. if we connect serial capacitor whole circuit working differently.

Hi sir.. The video was nice... But my doubt is how to find the component is purely resistive or reactive by impedence triangle diagram... From clip 16:49

[@blessoneasovarghese9834]

In impedance triangle, if resistance is zero, p.f. will be 0. if reactance is zero , pf will be 1

[@nayan2596]

What does negative power factor signifies?

[@arvindoh3687]

Same question

[@Syphus323]

Negative power factor means the circuit is capacitive , so you would have to add an inductor in parallel to bring the power factor to unity
