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