- How to improve Power Factor? PF correction and improvement with the capacitor with a practical demo project are explained in this video tutorial.
How Power factor correction or improvement is done by using a capacitor in parallel to the inductive loads or loads with low power factor, is explained.
Further, the power factor value is measured in this experiment for tube light, CFL lamp, LED bulb & fan and compared. The method of PF improvement and correction for tube light is explained in the lecture.
The value of the capacitor used is 1 microfarad each with a 2 M ohm resistor in parallel. An educational tutorial on electrical engineering 164 by G K Agrawal.
The lecture is given by a person with industrial experience and is useful for electrical, electronic communication, and power electronics engineering students, project work, and also Physics students.

R/SIR
I LIKE YOUR P.FACTOR VIDEO ,SIR WHAT IS THE VALUE OF THE CAPACITOR
IAM ALSO RETIRED PERSON
BUT SIR THE TEACHER IS NOT RETIRED UNTILELED THE LIFE......
1- Thanks, I we continue to spread knowledge, we are never retired.
2- Value of capacitor is 1 micro F each.
1 micro faradey , 250V AC
THANK YOU SIR.....
I THINK THAT WORKING VOLTAGE IS MORE THAN THE 250 V AC.
1- My house voltage is about 240V. But I used for short time for demo only. If we want for long term use, then we should take about 400V ac type for good life. This is to take care over voltae, voltage spike etc.
2- Best is, to replace choke type tubelight with LED bulb / LED tube light. Within 1 year entire cost may be recovered.
Sir why we use 400v for long time how I calculate it also i want to know about How I select right Capacitor bank or capacitor for power factor Improvement.......How and where we connect this capacitor..........
Waah dada g kmal ka sikhate hai 😀.
Sir.. I read your s.chand text books during engineering but now i am watching your videos... Good teaching style..
I have not written any book. Jai Hind
G K Agrawal... Sorry sir.. The author name is R. K. Agarwal.. Just small confusion.. Anways thank you for ur reply..
Very good presentation . Thank you.

मेरी अंग्रेजी अच्छी नहीं, 40 साल पहले मैंने सब हिंदी मीडियम से पढ़ा था
Practical informative video. Thank you
Great job sir g
Excellent Sir
thank you very much sir
Realy very good explanation .....sir thank you so much ..for all videos
Hi... Thank you sir .this is verry use full & helpfull video.
How to selction capacitor .
Watch my 2 videos, 1st video VA Watts kvar difference, and 2nd video HP, KW capacitor calculation.
I Don understand why 27 dislike d video??? Great video n great explanation wid practical... Awesome....
Whatever good thing we do, some people will dislike it. Similarly, whatever wrong or bad thing we do, still some people will like wrong thing. We have to live in this kind of society. We have no option. There is nothing in this world, which everybody likes or dislike.
Very good video can you give us please the features of capacitors witch kind thanks
See description.
Sir you are awsm
the video is excellent but I want to know how to choose capacitance value with respective to load
Required kvar=Pin kw(Tan(Present pf)-Tan(Required pf))
thank you sir i like yours pf video i think this is much more knowledge for peoples here i see some peoples are comment nucens you mind sir you make videos yours videos is very important in new generation students bcoz you are retired person still you supported peoples i heads off you sir i m very proud of you sir.
Hello sir please explain about meger testing procedures
Thanks u Sir. Plz make a video about capacitor series with 💡...same like this 📷....
Comments welcome
G K Agrawal not working.... if i connect that same circuit, amp reading increase instead of going down
check your circuit for conections again.
I already did... i check my connections same with the diagram
2 what is battery voltage
what is load, if load pf is v good, then pf will become bad and current will inctease, or if capacitor value is more, pl tell your load and capacitor value
This video is just a tutorial to help you understand PF of various devices. But our respected sir never said that reducing the PF will actually reduce your power bill. Lower PF will just increase your reactive power(not real power). And our meters are designed to measure real power only. But yes this lower pf increases the load(by increasing the current) on supply power momentarily. So for a heavy industry, the load on the wire increases significantly. This does not change their real power consumption but the momentarily increase in current increases their max demand graph thus making them pay more for fixed charges. For example if you run a low pf device with real power consumption of 2 KW but reactive power of 3 kw, then govt would charge you fixed charges for 3 kw, however, you never consumed a real power of more than 2kw. For industries this gap is huge and they end up paying more. So they go with using these capacitors.
And of course, adding an unwanted set of capacitors will surely increase you power consumption little bit. It will consume like a 20W led bulb constantly..
Good, watch my video on, problem of low pf and why we need to improve power factor in industry. There are many more problems with low power factors.
Good
Hello sir
your videos to good and sir I want you. you will make video electrical train concept and circuits diagram and which type current flow on train ..please sir
1- Video are available in Hindi and English both
2- watch train turning in hindi ua-cam.com/video/uSBW_fWMRb8/v-deo.html
dear sir kia air conditioner ka bhi load kam kia jaa sakta hai
R/Sir
This is very good class
Welcome
Can we install at our homes to improve pf.
In our homes we use AC, tubelights, Induction heater,
Not recommended.
@@GKAgrawal2 thanks sir for replying
Sir ek question hai hum agar house wiring me 1.5mm wire ki jagah 2.5mm wire fan k liye aur light k use karen to kya hum material waste kr rhe hain wire ka ya fir sahi hai 2.5mm use krna plz answer sir ji...
Sir inverter pe agar me 1/2 hp ki motor run kr ke and capacitor use krke kya inverter ka power factor improve kr sakta hu
I am suffering from some peoblem that is i used to add an essential load of factory to a 11/4. 33 v 1600 kva trns but when there is no inductive load in factory except the essential load (led,fan, single phase motor etc) the power factor go led
What is the cause can you please be know the fault took place and where from the pf leding. Please oblige me by knowing the fact
How can somebody solve your factory problem. Get the electrical system checked with some consultant.
good day my friend... can you give me idea what is the value of capacitor if I use a 1hp aircon.. thank you
Check rating plate of the motor and watch my video HP to KVAR and capacitor value conversion
will 30uf capacitors work better?
No, it will reduce pf,
Sir apfc panel kvar calculation bataiye hindi me , 1 se adhik load ke liye please.
sir, voltage Kam ya adhik hone par power factor me Kya effect padta h , please reply sir
Thank you
Sir can you provide secification of capacitor using in this project
And connection daigram
It is written in the description below video.
@@GKAgrawal2 thank you sir
What are the ratings of capacitor?
Sir ignitor ke uper ek vedio banaye
Sir power factor meter kitne ka hai
Hi Sar power factor is .99 ok this time energy meter slow or faster running.tell me sar please.
Sir ye led bulb or cfl ..ye power factor ko improve kaise karte hai..?
Sir what is the purpose of use 2 M ohm resistance in parllel
That is discharge resistor as told in video. Watch video once more.
sir, make a video of magneton , RF, different between ground vs earth, ckt I to v & v to I , f to v , v to f, I is current, v is voltage, f is frequency , traod tube ,tetrod .
Sir how does the current reduce in the circuit when we add another electrical pathway in parallel. Moreover the capacitors are outside the load circuit. Please explain
Watch my video on how leading and lagging power factor with calculation example.
Good explanation sir
In india electrical frequency is 50hz why sir pls reply mee
We got technolohy from UK/British, and there frequency was 50 Hz.
Sir what is the values of resisters
As many have asked this question, so It is written in the description.
Sir .
Agar poore ghar ka load 10kw hai ..(with all equipment on ).
Toh power factor kaise pta chalega ..
Konsa ik instrument use hota hai jisse power factor pta chal ske ..or uske bad ye calculate karna hai k 10kw load pe kitne KVa ka stablizer sufficient hoga. .
Ye sab power factor se pta chlega so ghar ka power factor pta krnae ka method btaen...
Thanx ..
Sir , power factor cum hone se our electric bill badega hey kya ?
Gharo mey PF penalty nahi lagti hai.
Can the power bill get less by improving pf .i mean in indusries they charge for low pf but in domestic power they donot charge for low pf .do we get less power bill in domestic power or not ?
Saving will be only in industry.
@@GKAgrawal2 sir i have another doubt that do domestic energy meters read real power energy or apparant power energy.please share ur knowledge on this.
hello sir plzzz explain the term power factor in electrical
Watch video ua-cam.com/video/PpznZLu7kpI/v-deo.html
Sir jib aapne switch ko on kiya tab amp. Kam ho gya tha . To kya es tarike se hum mitar ka bil kam kar skte hen
Ghar mey meter kaa bill power consumption sey aata hai, current sey nahee.
g k sir 2 capacitor lagaya tha 3.5/2.5 ka lekin ampear ghatne kea wajha ulta ampear Barbra hea kyu sir iski wajhe batai
capacitor jyada ho tho ulta hota hai, capacitor sirf jaroorat ke mutabik hee lagate hai,
dear Sir,
I like ur all lectures on electric but I request you please upload about ATS i,ll be very thankful you.
kind regards,
ats full form?
Automatic transfer switch
Sir kya power factor improve krnay say bijli k bill me kmi ati hay? 1 video me btaya gya hay k KW me koi kmi nae ati. Kya asa hi hay?
Kw mey koi kami nahi aati hai.
Industry mey power factor penalty lagti hai, so industry mey power factor correct karna padta hai.
What kind of capacitors are those?
Metalized polyester, AC,
kya capacitor lagane par capacitor ka bhi kuchh consumption hota hai?
aur agar pf 1 hai aur cap lagaya to kya effect padega?
cap relay settings kaise karni padti hai?
pf 1 hai , phir bhee capacitor laga diya tho pf kharab ho jayega.
sir, make a video about Op-amp please.
op amp part 1 and part 2 by g k agrawal search kare
what is the value of resistor & capacitor
See description.
what is the values of capacitors and resistors how to calculate plz explain with examples with load
thank u sir
load
In this video capacitor is 1 micro farad. Discharge resistor is 2.2 M ohm
sir in our plant we were producing 340MW,freq 50.1,
mvar -63 and mva 342.
so is this 340mw real or apparent power...??
What's the capacity n make of power factor meter,can we measure above 20kw load,how it will be connected.
It is suitable for small load, I connected 1KW load, it is not able to take.
Sir can I ask question??? If we improve PF, domestic side any benefit in light bill means kya mara light bill cum ho jayega???
House me power factor penlty nahee lagtee hai. Lekin power factor theek hone se fayede neeche likhe hai.
1- Wire aur switch me current kam ho jayegee , to wire loss kam hoga, wire garam bhee kam hoga.
2- Agar UPS hai to chota size kaa ( less KVA) lagegaa.
Aapne video me dekha hoga kee, LED bulb kaa power factor good hota hai aur power bhee less hotee hai. Aap LED bulb ya lED tube light kaa use kare.
G K Agrawal thanks sir for given answer
Sir according to your connection I can see phase difference in CRO or DSO or not.
Yes. You can see.
but Sir phase difference is very less that is around 1.12 micro second
then I am using Theta =2*pi*f*time
then PF=COS (Theta)
then it is coming around 0.93
On chock pf = 0.5 is written
power factor improved only all inductive load. Resistive Load pf allready unity. So why resistive load can used pf?
there were 3.15 mfd capacitor using what happen ???????????????/
What is the capacitor value
I have answered this earlier. Pl see all comments for this video. As this video was made long back, I do not remember the value.
Sir , I tried it at home using fan capacitor with the same connection as yours ... But instead of improving the power factor ,the power factor goes down .. how this happened sir? Thank you
Use a smaller value capacitor. I explain the reason in another video How leading power factor
Ok sir tq
is cfl inductive load...???
anyone pls explain
Sir y we not use pf bank in homes.
Y we use pf bank in industry.
1- In homes, load is less and PF penalty is not there.
2- In Industry Load is to much, and PF penalty is also there.
tq sir
Capacitor values???
It is written in the description
@@GKAgrawal2 thank you sir
sir mitar ka nam kya hai
Micro power monitor
y we should improve power factor sir actually power factor means loss of power na
low power factor means loss of energy ,
How bad and how good
Tell us in proper way
How can check value
It is TRUE that capacitance in parallel with the load WILL increase your power factoe BUT electricity companies do not charge your bill based on power factor . The amount of REAL power consumed is the same so your monthly bill will NOT decrease I am unhappy to tell you . Do you NOT think that a PFC or power factor correction device for residential premises would be selling by now like hot cakes . Of course it would BUT it does NOT.
In college you study and gain knowledge on many thing which are not used in homes.
You get knowledge on many thing which you may not use in full life.
PF penalty is very much there in the industries and they should learn the concept.
Even in home also, someone can use this knowledge and try to reduce current and losses in cables.
It is sad that you want to learn only those thing which are usefull in home only, that to just by imagination that it will never be useful in home.
Gaining knowledge is always good.
English is not coverage . Too poor English
