kVAR to Amps Calculator:
Enter the kVAR, then choose single-phase or three-phase. Then press the calculate button to get the results of reactive current in amps. While choosing three-phase enter the line to line voltage.
kVAR to Amps Calculation Formula
The flow of current I(A) Amps is equal to the 1000 times of reactive power in kilo Volt amp reactive Q(kVAR) divided by the voltage V(V) in volts. Let write the formula for kVAR to Amps conversion formula as below,
For single-phase,
I(A) = 1000 x Q(kVAR) / V(V)
For three-phase,
While considering the phase voltage,
I(A) = 1000 x Q(kVAR) / 3 x V(V)
While considering the Line voltage,
I(A) = 1000 x Q(kVAR) / (1.732 x V(V))
Example 1:
Let we calculate the flow of current in Amps for 1kVAR capacitor bank connected in single-phase power supply at 230 volts, 0.9pf.
Let apply our formula
Current in Amps I(A) = 1000 x 1 / (230)
Current = 1000 / (230)
= 4.3 Amps reactive
Hence 1 kVAR capacitor bank shall give you 4.3 A at 230 Volts.
Example 2:
Let we calculate the reactive current for 25kVAR capacitance bank which is connected to three-phase at the line voltage of 415 volts.
Apply our three-phase reactive current formula,
Current in Amps I(A) = 1000 x 25 / (1.732 x 415)
= 34.78 Amps
