Description

Used to measure or scope in 3-phase mode the Active Power (in W), the Reactive Power (in VAR), and the Apparent Power (in VA).

$$P = \frac{1}{T} \int_t^{t+T} v_a(t) \cdot i_a(t) \cdot dt + \frac{1}{T} \int_t^{t+T} v_b(t) \cdot i_b(t) \cdot dt + \frac{1}{T} \int_t^{t+T} v_c(t) \cdot i_c(t) \cdot dt$$

$$Q = v_{a1} \cdot i_{a1} \cdot \sin(\phi) + v_{b1} \cdot i_{b1} \cdot \sin(\phi) + v_{c1} \cdot i_{c1} \cdot \sin(\phi)$$

$$S = v_{a rms} \cdot i_{a rms} + v_{b rms} \cdot i_{b rms} + v_{c rms} \cdot i_{c rms}$$

where $x_{rms}$ is the RMS of $x$ and $x_1$ is the fundamental of $x$
