I,m a electrical design engineer. I have desingned a capacitor bank load for a traansformer. for that to find the load of the capacitor bank i have used this formula (I = VAr /(1.732*V)). why shouldn't we use sin phi there? Please tell me the answer and explain the concept.

Is capacitor bank taking load? If yes then why is not shown in ammeter of main line?

 If your not sure on your calculations using the above formula, use a Power Analyzer device (ex. AR5L Power analyzer by CIRCUTOR). Connect the device to the line where the capacitor bank was connected.(make sure the system was energized and on operation, as well as the capbank)
You'll see in the device the electrical parameters that will answer to your question. This device also will determine the problem on the electrical system where it is connected such as flicker, voltage sags, swells and distorted harmonics.

The current flowing to the capacitor bank is assumed to be purely capacitive and so the only opposition to current flow is capacitive reactance so phase angle is irrelevant. Anyway the phase angle would be 90 degrees sin 90 = 1 and so would make no difference to the answer.

The circuit to the capacitor bank is considered pure and so the phase angle would be 90 degrees. sin 90 = 1 and so would make no difference to the answer.

KVAR = Kw * Kw factor Kw  is the total peak load and kw factor value from kw factor table based on your current power factor and targeted power factor)

Because electrical power have 3 different angle... cos and sin.. cos is kva.. sin is kvar...
