Sir, thank you so much. This is going to add to the basics of my panel design learning. No one is ready to tell such calculations in the company during the work
Always welcome❤
Thank you very much sir, this is very helpful for my basic learning APFC panel manufacturing.
Glad it was helpful!
Really it's very useful video for beginners. Thank you
Welcome 😊
Hi sir ... I'm inspired from your video ... I learned lot from you ... Thanks for the videos ...
Welcome 😁❤
@@ElectricalInfinity sir can I get your number
very simple and user friendly explanation , all the best
Thank you sir ! Glad you like it.
Very good keep going on also make a video on Voltage drop calculations for cables , Bus ducts & Rising mains...
Thank you.
Thank you sir
Thank you bro
We need a video of Auto transfer switch from Main line to DG..
control connection
Power connection
Inputs of DG
Everything sir
Please we need a clear video sir please
me also
Very good explained 👌👌
Thanks
Hi sir in my company we have 1250 kva transformer. Explain about apfc calculations pls. I am a new one
Sir you are explaining such a great way......sir please make a video for substation design
Thanks 😊
What should we do if APFC showing Capacitive load and Power factor is in negative
Hi,
can you please make a video of apfc relay if the plant has bidirectional power flow as netmeter in Solar
Please make another video on apfc panel regarding
1.how to make stages of capacitor
2.fixed and variable capacitors
3.how to overcome harmonics problems in power factor improvements
check the description and watch power wiring of apfc panel for stages and fixed variable capacitors.
will make one on harmonics soon. Thanks :)
Sir
Mera apfc panel 15 kw ka he
aur me testing kr rha hu total
3 motor ( total 3 kw ) at no load ,
Meri apfc relay sahi work kr rhi he
But thodi der baad
"CURR: Phase current error " likha aa jata he
Kya apfc relay ko work krne ke liye
Kisi minimum load ki requirement hooti he ?
Please reply
I have digital utility bill in different sites of client,can you help me APFC sizing
Good job, keep growing.
Thanks you bro ❤
Dear sir ,
We need truff dimensions calculation and need compartment dimensions clearance based on circuit breaker, cable alley dimensions for based on cable
Superb
Thanks 😍
Helpful video, could you please tell how to calculate mail branch circuit breaker rating? If we have KVAR rating given. For example for 600KVAR what will be the value of incomer circuit breaker?
Hi sana, thanks for appreciation. You can watch this video in which I explained about apfc panel circuit breaker selection.
@@ElectricalInfinity dear sir thank you for reply your content is really helpful for me me. I have some doubts. First while calculating CB rating for TF why we are multiplying by 1.4?
2. I have seen a thumb rule KVAR×2.32= Ampere ( for CB) and you have taken value of 2? Could you please explain this?
For 3 phase to convert kva to ampere multipying factor is 1.4. For Kw to amp it is 1.9 and for HP to Amp it is 1.5. You can this video for more clarification ruclips.net/video/5PHyLUGkl14/видео.html
@@ElectricalInfinity got it thanks
Sir one doubt
For example
3ph motor connecting load is 40kw
1ph motor connecting load is 10kw
Lighting load is 5 kw
Total connecting load is 55 kw
How to estimate befor pf kavr value
Bro we need more videos
Sure bro. I was busy with work commitments but now I'm back
Can you explain please, why we are taking 40% and 30% of 2500kva
Make video on pcc & mcc C.B calculation
40 % of 1250 kva is 500 kvar
30 percent 0f 1250 is 375kvar
But when we follow kw method , kva x.8 ,1250x.8 is 1000kw,1000kw x .266 =266kvar
(For .8 to .9 pf)
Both calculations are not matching ,please reply
Any one who knows please reply
Do u train people
Is it applicable to new installation or to improve existing capacitor bank
Yes it is
While I am doing I got the answer like this Cos^-1 (0.8)= 0.64535 and Cos^-1 (0.9)= 0.4510... but you were put like Cos^-1 (0.8)= 36.86 how is possible pls clear me
You are getting values in radians. Do it in degrees
which software we can use for electrical design
AUTOCAD, MATLAB, MULTISIM
@@ElectricalInfinity can you make a video of designing control panel by using software
Make correction's in video...
pf= P/S not P/Q
I am sorry, I didn't got you. can you explain ?
At 1.09 minutes
Power factor (cos)= Active power (P)/apparent power(S)
Pf= Cos(Φ) = P/S = W/VA = power factor.
The power factor is calculated as the ratio of the real power to the apparent power.
Also Real power= apparent power ×power factor.
You can do some more research on this. What you say is correct and basic formula but once you go Deep into calculations P= Real power/ apparent power make sense.
Sorry for late reply ☺️.
I can answer in more details but short of time. Thanks for watching
Please tell solwly sir can't understand 😔
Sure
Pf = active / apparent
Not active/ reactive
Make corrections
Pf= Cos(Φ) = P/S = W/VA = power factor.
The power factor is calculated as the ratio of the real power to the apparent power.
Also Real power= apparent power ×power factor.
