Abstract: An electrical utility meter includes measurement error diagnostic capabilities with intelligent communication capabilities. In an exemplary embodiment, the present invention includes an electrical utility meter for measuring energy consumption by a load. The electrical utility meter includes, sensor circuitry, a conversion circuit, a communication circuit, and a controller. The sensor circuitry connects to a meter socket. The meter socket connects to a plurality of power lines that, in turn, connect the load to a source of electrical power. The source of electrical power provides power to the load in a plurality of phases. The sensor circuitry generates voltage and current measurement signals representative of the voltage and current waveforms on the plurality of power lines.
