PF = \ Cos Ҩ\ = 1000 X P (kW) / (3 x V L-N (V) x I (A))Ĭalculation of the correction capacitor's capacitance Ĭ (F) = 1000 x Q (kVAR) / (3 x 2∏f (HZ) x V L-N (V) 2) Line to Neutral Voltage Calculation of the power factor \S (kVA)\ = √3 x V L-L (V) x I (A) / 1000Ĭalculation of the power factor correction capacitor's capacitance Ĭ (F) = 1000 x Q (kVAR) / (2∏f (HZ) x V L-L (V) 2) The power factor is equal to the cos Ҩ and is computed by PF = \Cos Ҩ\ = 1000 x P (kW) / (√3 x V L-L (V) x I (A)). The power factor correction capacitor's capacitance is computed by C (F) = 1000 x Q (kVAR) / (2∏f (HZ) x V (V) 2)Ĭalculation of the Three Phase Circuit Line to Line Voltage Calculation Q (kVAR) = √ (\S (kVA)\2) – P (kW) 2) is the formula for calculating the reactive power PF = \ Cos Ҩ\ = 1000 X P (kW) / (V (V) x I (A)), which is the calculation of the power factorĪpparent power is calculated by multiplying the voltage in volts by the current in amps divided by 1000. If you are using the three phase, then you will need to select the type of energy.Īfter all the values are entered in their required text fields, you can click the ‘Calculate' button which executed the computation. You need to enter the real power in Kilowatts, current in amps, the voltage in volts and frequency in hertz.
To calculate kVA, you need to enter the known values of voltage and the current into the respective fields. You start by first selecting the phase which may be single or three phase. Single & 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. It is used to calculate the apparent power, power factor, correction capacitor's capacitance and the reactive power.
