3.5.6 Vector Power Quantities

Here are examples of some of the possible vector power quantities that may be computed (note that there are multiple definitions for vector power quantities, and the symbols used can vary, such as "U" and "S"):

Where, x = [A, B, C] and:

• U_x is apparent power of all harmonics of phase x
• S_x is phasor power, all harmonics
• D_x is distortion power, all harmonics
• F_x is fictitious power, all harmonics
• N_x is nonreactive power, all harmonics
• U_aa is system arithmetic apparent power, all harmonics
• U_va is system vector apparent power, all harmonics
