Find the MVARs needed to achieve a power factor of 99.8% .
The transformer rating is 650 MVA.
Active Power =
Reactive Power Needed = plus or minus
Calculated VAR support needed to achieve the target power factor (If your input is VA) or
kVAR support needed to achieve the target power factor (if your input is kVA) or
MVAR support needed to achieve the target power factor (if your input is MVA)
Step 1. Click the clear button
Then enter VA or kVA or MVA . Next go to Step 2 enter desired power factor. Finally select button Solve, Q.
Given
VA or kVA or MVA

Step 2. Enter desired power factor in percent, do not enter the percent symbol
Desired Power factor in ( % ) = %
To do scenario analysis, simply raise the target power factor and solve for the needed VAR or kVAR or MVAR support.
Angle Theta θ = °
Formula Recall
S2 = P2 + Q2 ; Using Pythagorean Theorem
