Customer ServiceSingle & Three Phase Line kVA calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. To calculate kVA, you need to enter the known values of voltage and the current into the respective fields.
Customer ServiceThis means a capacitor with 100kVAR name plate data could deliver anywhere from 100-115kVAR of reactive power and consequently draw larger current. It is usually possible to get the manufacturing tolerance from the manufacturer or measure the capacitance and determine the tolerance.
For the system shown in the picture above, capacitors are rated at 400kVAR at 7.2kV. Individual capacitors are connected line-neutral. The System line-line voltage is 12,470V. The net rating of the bank is 400*3=1,200kVAR. To calculate the full load current, enter 1,200kVAR as rating and voltage as 12,470V in the three phase calculator above.
The voltage at which the capacitors are applied can vary +5% or even up to +10%. Voltage less than nominal is not a concern for as the lower voltage will result in lower capacitor current. Harmonics can create additional current flow in the capacitors any where from +20% to +35% of the rated current.
