Reactive to Apparent Converter
How to Use the kVAR to kVA Calculator
Follow these simple steps to use the kVAR to kVA calculator:
- Step 1: Enter the value of reactive power (kVAR).
- Step 2: Enter the power factor (PF) of the system.
- Step 3: Click the calculate button.
- Step 4: The calculator will instantly display the apparent power in kVA.
Tips:
- Use accurate power factor values for better results.
- Typical power factor ranges from 0.7 to 1.0.
- Always double-check input values before calculating.
How to Convert kVAR to kVA
To convert kVAR to kVA, use the formula:
Where:
- kVA = Apparent Power
- kVAR = Reactive Power
- PF = Power Factor
Step-by-step example:
Given: kVAR = 50, Power Factor (PF) = 0.8
Step 1: Square the power factor
PF² = 0.8 × 0.8 = 0.64
Step 2: Subtract from 1
1 - 0.64 = 0.36
Step 3: Take square root
√0.36 = 0.6
Step 4: Divide kVAR by result
kVA = 50 / 0.6 = 83.33 kVA
