2.6 DSP Channel and Computed Quantity Description

DSP channel nomenclature defines 3 basic voltage channels: V_A, V_B and V_C, and 4 basic current channels: I_A, I_B, I_C, and measured neutral current, I_Nm. The channel currents are combined to create an accumulated imputed neutral current, I_Ni, and an accumulated sample-by-sample difference between the measured and imputed neutral currents, I_Nmi.

Values further labeled as '_F' indicate values associated with the fundamental frequency component only, while values without the '_F' indicate values associated with fundamental + harmonics.
