Electronic Power Meter and Method of Temperature Compensation Using the Same

摘要

The present invention relates to an electronic power meter. The electronic power meter according to the present invention comprises: a temperature sensor; an analog-digital converting unit that converts an analog signal conveyed from an electric current channel and a voltage channel into digital; a temperature compensation unit that performs temperature compensation of the electric current and voltage converted into digital; and a power calculating unit that calculating the power by multiplying the compensated electric current and voltage. It can more accurately add up power as it performs the temperature compensation of electric current and voltage before calculating power and calculates power with the value.
