The total active power P in a balanced 3-phase system expressed in terms of line voltage V_L and line current I_L is:
A3 * V_L * I_L * cos(phi)
Bsqrt(3) * V_L * I_L * cos(phi)
Csqrt(3) * V_L * I_L * sin(phi)
DV_L * I_L * cos(phi)
Explanation
Three-phase active power P = sqrt(3) * V_L * I_L * cos(phi) or 3 * V_ph * I_ph * cos(phi).
