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)
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.
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
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
The most accurate method of selecting a capacitor is to take the no load current of the motor, and multiply by 0.90 (90%). Example: Size a capacitor for a 100HP, 460V 3-phase motor which has a full load current of 124 amps and a no-load current of 37 amps. Size of Capacitor = No load amps (37 Amp) X 90% = 33 Kvar Go to Content ↑ 2.
Size a capacitor for a 75HP, 460V 3-phase motor which has a full load current of 92 amps and an unknown no-load current. No-load current of Motor = Full load Current (92 Amp) x 30% = 28 Amp estimated no-load Current. Size of Capacitor = No load amps (28 Amp) X 90% = 25 Kvar.
