How to calculate the value of capacitance of a capacitor
used in power factor improvement plant if we know KVAR and
voltages?



How to calculate the value of capacitance of a capacitor used in power factor improvement plant if..

Answer / raviteja vaka

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

It is a three inch fan and i want it to rotate to other direction .I've tried cutting the wire and reconnecting them inverse like black to white and white to black ,but it won't start rotating when i plug it in that way.And then it works again when i rejoin the wire to the way it is. I don't know what causing the problem.Is there anyone familiar with these small mortor?Any suggestion would be appreciated.Thanks!! http://i296.photobucket.com/albums/mm163/sasukebloodwheel/110527-105859.jpg
