AI Customer ServiceHence 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)
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.
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.
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.
Some of the variable that determine the capacitor bank current are: KVAR TO AMPS CALCULATOR – THREE PHASE KVAR TO AMPS CALCULATOR – SINGLE PHASE For example 25 kVAR capacitor current can be calculated to be 4A for a 7,200V single phase system with 10% capacitor tolerance and 5% voltage tolerance. Power Factor Calculator
This 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. Voltage Tolerance
