#How to calculate KVAR #Capacitor Bank Sizing #APFC Panel #Electrical System #Tamil #
APFC Stands for automatic power factor correction/controller
KVAR stands for kilo volt ampere reactive
Assume that your electrical distribution system have the value of 100KVA,415V,240.96 Amps and PF is 0.8.
If we want to improve the power factor from 0.8 to 0.99, you need to install the static capacitor in the existing system.
There is a standard formula to calculate the required KVAR i.e.
KVAR =P(Tan pi 1 - Tan pi 2)
Let us assume Cos Pi 1 = 0.8
Pi 1 = cos inverse of 0.8
Pi 1 = 36.869
Also let us assume Cos Pi 2 =0.99
Pi 2=Cos inverse of 0.99
Pi 2= 8.109
Now apply all the known values into the KVAR standard formula.
KVAR= 100( Tan 36.869 - Tan 8.109)
=100(0.749-0.142)
=100(0.607)
=60.7
So, to improve the power factor from 0.8 to 0.99, we need to install at least 60KVAR capacity of APFC panel in the electrical system.

Brother thank you very much very good explanation please continue thanks 🙏

[@mad-maker.]

It's very use full info bro. Thanks a lot

[@AK_GLOBAL_KITCHEN]

Nice Explanation bro

[@kailashv1775]

Thanks u bro very use full

Super explanation

[@senthilkarthik9268]

Good explain super sir

[@allinallaravinthcena3000]

Is very useful tq sir

[@dharmadasadushyantha1108]

i cant understand tamil, but ur prasantation great, can understand anybody, who has ellectrical knowkkedge, pls presant how wiring that cap bank,

[@blueline008]

Good... Thank you

[@priethikaanbarasan4815]

HP to kvr calculate pantrathu yeppati bro

[@sanjaikumar5931]

What capacity of capacitor bank suitable for 3hp 3 phase motor to increase pf

[@rajarajendran7656]

Super very yous full pro

[@abdulazeez4930]

Sir one doubt for example ore 60kva motor load new factory la befor ra vea yappadi munkutti kvar reating ga calculate panrathu without connecting load

[@prabhuk7359]

Thank you sir

[@bharathiraja9929]

Super 🔥🔥🔥🔥

[@yamanappae3095]

How much capacitor used for 60kvar..

[@sathiyanathan100]

Super

[@engineertechnology823]

Please explain reactor Woking and principles

[@bharathiraja9929]

3 phase capacitor yappate check pantrathu bro...

[@baskarrambas651]

Give details of capacitor values to related hp motors of single phase and three phase motors sir

[@ashoksrinivasan3288]

For 70 kw load how much Capacity bank we must put sir ?? As i am getting fee high for it

[@magimanila695]

Hi bro., 500 KVA ku capacitor bank value yevaluve varum

[@vimalraj2165]

10hp motor how to choose capacitor Bank rating tel me

[@usuthay]

Supper brother ❤

[@usuthay]

It is very helpful

[@EngineersViewEEE]

🤝

[@evanz5984]

Vsd drive calculation and energy saving formula and calaculation solluga sir

[@senthilkumar-zr7vb]

Bro cos inverse of 0.8 value = 36.86 shown. But ur value different. Pls explain.

[@gdbenji3278]

Can we use for home

[@BALAGURU13]

Hi,
I have using 5hp 3p motor and 2 HP 3p motor. Now our energy meter showing APF 0.58.
So TNEB person advise the capacitor bank for line . Please suggest me which capacitor bank suitable for my motors.

[@ganesan21384]

5hp ku 3kvar,2hp ku 1 kvar use panuga

[@k.pselvam7445]

Capacitor good condition check sir

[@RajKumar-lf9fj]

Every person know about this formula. But you have to separate 60KVAR to PER phase(R, Y, B)

[@saravananpoomalai5382]

How reduce leading power factor for function hall very minimum lighting load.

[@EngineersViewEEE]

Are you using capacitive load ? Let me know to suggest further

[@mathankumar2502]

Simple method solunga bro

[@EngineersViewEEE]

Sure brother

APFC panel 85kvAR power factor 0.996.&7 varuthu so inum 0.99 Vara Enna pannalam plz... Sher me

[@mohamedlathiff5553]

Inductive load la concentrate pannuga improve panlam ..

[@ashokraj2786]

Bro New load add for 148 kw so Lt panel mwh.L1.099 L2.099 L3.099 varuthu but APFC .60kVr tha ithu eppati pf maintanence akutha check meter la

[@ebenezer1843]
