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:
C(F) = 1000 × Q(kVAR) / (3×2πf(Hz)×VL-N(V)2)
