Abstract
A differential coupling path is provided for power measurement communication between a host device and a line side device. The line side device couples to AC power grid to extract voltage signals and current signals using various voltage and current sensors. The extracted voltage signal and current signal are converted to digital signals by internal A/D converters within the line device and then sent to the host device through the differential coupling path coupled between the host device and the line side device. The host device may couple to one or more line side devices via multiple differential coupling paths.
