I know the Capacitor value- 12.5KVAR, voltage 440V gas
filled, then what is the formula for calculate the
microfarad value for this 12.5KVAR capacitor
Answers were Sorted based on User's Feedback
Explanation:
Q=Reactive Power in VAR
U-voltage at capacitor terminals[single phase]in Volt
frq=frequency[50 or 60 HZ=cycles/second]
Q=U^2/Xcap Xcap=Capacity reactance [in ohms]=1/(w*Cap)
w=2*pi*frequency
Then Q=U^2*w*Cap or Cap=10^9*Q/(U^2*2*pi*frequency) if Q
is in kVAR and capacity in microFarad.
If U is the line-to-line voltage the same formula is good
for three-phases in Y but Q=3*U^2/Xcap for delta connection.
