How to calculate the value of capacitance of a capacitor
used in power factor improvement plant if we know KVAR and
voltages?
for 3-ph system
Kvar=Sqrt(3)*v*i*sin(phi)
or Kvar=kw*tan(phi)
and for value of capacitance when kw or kvar is known
c=KVAR/(2*3.14*f*v^2) when capacitors are connected in Star
c=KVAR/(6*3.14*f*v^2) when capacitors are connected in Delta
I think the above information is in line with your question
If u want any further details mail me @ raviteja.vaka@gmail.com

How isolater function when installed inelectrical 440V wiring
What is the basic principal, by which DC voltage level is increased more than the supplied AC voltage during conversion. As upto AC level it is contorrled by firing anlge but after maximum level how is it possible.Please clear picture. OR we have to supply the higher level AC?
I know during Surge Impedance Loading maximum power is transferred through a transmission line and also Sending end voltage becomes equal to Receiving end voltage i.e Vs=Vr so my question is if both end voltages are equal then how current travels in such line hence how power is transmitted because flow of current needs Potential difference??
