Calculate Reactive Power
To Increase Power Factor of A Network

Find the MVARs needed to achieve a power factor of 99.8% . The transformer rating is 650 MVA.

Active Power =

Reactive Power Needed =

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)

---

Easy to use: Click the white input box then enter new number. Or click the clear button then enter new number.

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

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.

Formula Recall

S² = P² + Q² ; Using Pythagorean Theorem

NaN means Not a Number , what it means is the calculated answer is a complex number.This calculator only allows real numbers. So when the answer is a complex number, NaN will appear. if you enter any letter in the input box, example letter O, NaN will also appear. If you enter comma sign , you will also get an NaN error message. Re-enter the number without comma sign.
