Single phase circuit formula:

Apparent power: |S(kVA)| = V(V) × I(A) / 1000

PF = |cos φ| = 1000 × P(kW) / (V(V) × I(A))

Reactive power: Q(kVAR) = √(|S(kVA)|2 - P(kW)2)

Correction capacitor: C(F) = 1000 × Q(kVAR) / (2πf(Hz)×V(V)2)

Three phase circuit formula:

line to line voltage:

PF = |cos φ| = 1000 × P(kW) / (√3 × VL-L(V) × I(A))

Apparent power: PF = |cos φ| = 1000 × P(kW) / (√3 × VL-L(V) × I(A))

Reactive power: Q(kVAR) = √(|S(kVA)|2 - P(kW)2)

correction capacitor's capacitance: C(F) = 1000 × Q(kVAR)/ (2πf(Hz)×VL-L(V)2)

line to neutral voltage:

Reactive power: Q(kVAR) = √(|S(kVA)|2 - P(kW)2)

correction capacitor's capacitance: C(F) = 1000 × Q(kVAR) / (3×2πf(Hz)×VL-N(V)2)

Apparent power: |S(kVA)| = 3 × VL-N(V) × I(A) / 1000

Power factor : PF = |cos φ| = 1000 × P(kW) / (3 × VL-N(V) × I(A))
