Current sensor error compensation method

A system for performing current sensor error compensation comprising:

• a memory;
• and
• a processor configured:
• to obtain a current measurement of a current on a circuit from a current sensor,
• to obtain a voltage measurement of a voltage associated with the current from a voltage sensor,
• to determine a fundamental frequency of the voltage from the voltage measurement, and
• to perform error compensation on the current measurement, by determining a compensation factor based on the determined fundamental frequency, and applying the compensation factor to the current measurement to produce a corrected current measurement.

A tangible memory medium storing computer executable code, which when executed by a processor, implements a method of performing current sensor error compensation, the method comprising:

• obtaining a current measurement of a current on a circuit from a current sensor;
• obtaining a voltage measurement of a voltage associated with the current from a voltage sensor;
• determining a fundamental frequency of the voltage from the voltage measurement;
• and
• performing error compensation on the current measurement, comprising:
• determining a compensation factor based on the determined fundamental frequency, and applying the compensation factor to the current measurement to produce a corrected current measurement.
