Standard energy meter and correcting method of sampled signals thereof

The invention relates to a standard energy meter and a correcting method of sampled signals thereof, wherein the method comprises the following steps of: adding a reference voltage circuit in the standard electrical energy meter, realizing the acquisition of each sampled signal through a corresponding selection switch, then sampling a reference signal once, comparing a sampling value of the reference signal with a stored original measured value to obtain an error compensation quantity and then carrying out error compensation for the acquisition quantity of the sampled signals, thereby effectively improving the equipment stability of the standard electrical energy meter after long-term use.
