Abstract
An electronic energy meter includes a first sigma delta modulator having an electrically isolated digital data output. A power supply stage coupled to a first electrical line provides a supply voltage to the first sigma delta modulator. A shunt device is also coupled to the first electrical line. The first sigma delta modulator is coupled via an input to the shunt device for measuring a current through the first electrical line. The electrically isolated digital output is isolated by a capacitive isolation barrier.
