VA to Amps :
VA :
- A volt-ampere is the unit for the apparent power in an electrical circuit.
- The apparent power equals the product of root mean square voltage and root mean square current.
- In direct current circuits, this product is equal to the real power in watts.
Amps :
- The ampere, often shortened to amp, is the SI base unit of electric current.One ampere is equal to 6.241509074×10¹⁸ electrons worth of charge moving past a point in a second.
VA to Amps :
- It is used to convert the apparent power in volt-amps (VA) to the current in amps (A).
Single Phase :
- I (A) = S (VA) / V (V).
- Which means that the current in amps is calculated by dividing the apparent power S by the voltage V in Volts.
Three Phase :
- I (A) =1000 x S (VA) / (√3 x V L-L (V)) = S (VA) / (3 x V L-N (V)).
- Which means that the current in amps is calculated by multiplying 1000 by the apparent power in volt-amps.
- The result is the divided by the square root of three multiplied by the line to line voltage in volts.
