Abstract: Certain aspects and features include a system and method for energy measurement in electric meter systems. In an example, an electric meter receives an Alternating Current (A/C) signal. The electric meter includes a current measurement device that is configured to obtain a current measurement of a current of the A/C signal. The current measurement includes a fundamental frequency component and a noise component. The electric meter receives a current measurement signal from the current measurement device and filters the noise component from the current measurement, thereby creating a filtered current measurement signal. When the filtered current measurement signal is greater than a starting current threshold, the electric meter calculates an energy consumption measurement.
