Abstract

An electric energy meter for a poly-phase electricity network includes a power transformer having a primary side and a secondary side, a first analog front end (AFE) unit is coupled to the secondary side of the power transformer, and a microcontroller coupled to the primary side of the power transformer. The first AFE unit is to be coupled to a first phase of the poly-phase electricity network. The microcontroller is configured to transmit a digitized request signal to, and to receive a measurement signal from, the first AFE unit via the power transformer. More specifically, the first AFE unit, upon receiving the digitized request signal, is to extract information from the digitized request signal.
