Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
This register contains the instantaneous apparent power delivered into phase A/B/C or total at the fundamental line
frequency only. Power is calculated from the instantaneous energy measurement according to the following equation:
This signed register contains the real accumulated energy delivered into phase A/B/C or total. The register is calcu-
lated according to the following formula:
This signed register contains the reactive accumulated energy delivered into phase A/B/C or total. The register is
calculated according to the following formula:
