1.2 How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs—Metrology architecture options: SoCs, AFEs, and standalone ADCs

Description

March 26, 2019
This module discusses three different architectures for sensing the voltage and current samples used to calculate the metrology parameters.  These architectures involve using a SoC, metrology AFE, or standalone ADC.   The advantages of the standalone ADC architecture compared to the other two architectures is discussed.  This is the second of two modules for the “Current sensor and metrology architecture options” section of the “How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs” training series.
