ABSTRACT:
Methods and systems for an electrical meter are provided. The meter includes a current sensor configured to be communicatively coupled to a conductor, and a processor communicatively coupled to the current sensor wherein the processor is configured to receive signals indicative of current flow through the conductor and wherein the processor is further configured to process the signals to determine an imbalance between the positive half cycle of the current flowing through the conductor and the negative half cycle of the current flowing through the conductor to detect a DC influence on the current sensor.
