Easily calculate total 3-phase power, power factor, reactive power, and apparent power using the two wattmeters method. Input your wattmeter readings (W1, W2) to determine key electrical parameters for balanced or unbalanced loads efficiently. Ideal for electrical engineers and technicians.
Formula:
Formulas Used:
- Total Active Power (P) = W1 + W2
- Total Reactive Power (Q) = √3 × (W1 - W2)
- Phase Angle (φ) = atan(√3 × (W1 - W2) / (W1 + W2))
- Power Factor (cos φ) = cos(φ)
- Apparent Power (S) = √(P2 + Q2)
Where:
- W1 = Reading of Wattmeter 1 (in Watts)
- W2 = Reading of Wattmeter 2 (in Watts)
- P = Total Active Power (in Watts)
- Q = Total Reactive Power (in VAR)
- S = Apparent Power (in VA)
