Answer / viswanath

the capacitor bank depends on the load type
1. for resistive load no need cap.bank
2.and the cap.bank calculation depends on the Power factor

(for inductive loads 0.8 pf lag)
if u want clear calculation mail me with all load perticulars

Answer / rohit pareek

the capacitor bank reqired almost 30 persent of full load
(kva) but exectly we must know the desired powerr factor

KVAR = kw/Sin theta

pf= cos theta= desired pf

let 0.99 we require than cos Q = 0.96
Q= Cos inv 0.96
SinQ Will = sin * Q

Kvar = Sin Q* Load

Answer / mior

First and foremost, you need to know what is your required
KVAr; then, you can design the capacitor bank to suit with
your required KVAr.

The purpose of designing the capacitor bank is to correct
the power factor to the desired value. By doing so, you can
reduce the loses of power as well as reducing your
electricity bill.

The link below might help you on how to design the power
factor correction and how to design the capacitor bank.

i have one transformer 1000kva, 11/.433kv. we are using 200/5 amp. ct unit for measuring purpose, & one 800 amp. V.C.B Unit for the same t/f operate, i wants to known the primary current of T/F is only 53 amp. why we used 800 amp. V.C.B ? & 200/5 amp. CT Unit.

If the load of transformer is getting more than its rating,,,than how to overcome this problem? Suppose thee rating of transformer is 315kva and the load is going beyond than the rating say around load: 352kva... Than how can we solve this problem without deducting the load.
