Calculation used for calculating KVA (Kilo Volt Amps):
Single phase kVA to amps calculation formula:
The current I in amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the voltage V in volts:
I(A) = 1000 × S(kVA) / V(V)
3 phase kVA to amps calculation formula:
Calculation with line to line voltage:
The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by the square root of 3 times the line to line RMS voltage VL-L in volts:
I(A) = 1000 × S(kVA) / (√3 × VL-L(V) )
Calculation with line to neutral voltage:
The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by 3 times the line to neutral RMS voltage VL-N in volts.
I(A) = 1000 × S(kVA) / (3 × VL-N(V) )
Calculation used for PF (Power Factor):
# The power factor correction capacitor should be connected in parallel to each phase load.
# The power factor calculation does not distinguish between leading and lagging power factors.
# The power factor correction calculation assumes inductive load.
Single phase circuit calculation:
Power factor calculation:
PF = |cos φ| = 1000 × P(kW) / (V(V) × I(A))
Apparent power calculation:
|S(kVA)| = V(V) × I(A) / 1000
Reactive power calculation:
Q(kVAR) = √(|S(kVA)|2 - P(kW)2)
Power factor correction capacitor's capacitance calculation:
Scorrected (kVA) = P(kW) / PFcorrected
Qcorrected (kVAR) = √(Scorrected (kVA)2 - P(kW)2)
Qc (kVAR) = Q(kVAR) - Qcorrected (kVAR)
C(F) = 1000 × Qc (kVAR) / (2πf(Hz)×V(V)2)
Three phase circuit calculation:
For three phase with balanced loads..
Calculation with line to line voltage:
Power factor calculation:
PF = |cos φ| = 1000 × P(kW) / (√3 × VL-L(V) × I(A))
Apparent power calculation:
|S(kVA)| = √3 × VL-L(V) × I(A) / 1000
Reactive power calculation:
Q(kVAR) = √(|S(kVA)|2 - P(kW)2)
Power factor correction capacitor's capacitance calculation:
Qc (kVAR) = Q(kVAR) - Qcorrected (kVAR)
C(F) = 1000 × Qc (kVAR) / (2πf(Hz)×VL-L(V)2)
Calculation with line to neutral voltage
Power factor calculation:
PF = |cos φ| = 1000 × P(kW) / (3 × VL-N(V) × I(A))
Apparent power calculation:
|S(kVA)| = 3 × VL-N(V) × I(A) / 1000
Reactive power calculation:
Q(kVAR) = √(|S(kVA)|2 - P(kW)2)
Power factor correction capacitor's capacitance calculation:
Qc (kVAR) = Q(kVAR) - Qcorrected (kVAR)
C(F) = 1000 × Qc (kVAR) / (3×2πf(Hz)×VL-N(V)2)
