1. A method for measuring electrical quantities in an electrical system, comprising:
obtaining a first set of known electrical output values via an electrical quantity sensor, the first set of known electrical outputs being associated with a first temperature measured via a temperature sensor that is different than the electrical quantity sensor;
obtaining a second set of known electrical output values via the electrical quantity sensor, the second set of known electrical outputs being associated with a second temperature that is different from the first temperature, the second temperature being measure via the temperature sensor;
measuring an operational temperature of one or more locations in the electrical system;
computing a pair of reference electrical output values, corresponding to the measured operational temperature, in accordance with the first set of known electrical output values associated with the first temperature and the second set of known electrical output values associated with the second temperature; and
interpolating among the pair of computed reference electrical output values to determine a temperature-corrected electrical quantity based on the measured operational temperature and the reference electrical output values.
