Abstract :
A high-precision power-factor meter, based on zero crossing detectors, is proposed. The influence of the distortion in the input signals is analyzed and low pass filters proposed to prevent this error source. This system is proposed as a new power standard meter, based on the measurement of voltage, current and power factor.
