Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0027] The procedure of the error debugging method of the electronic energy meter of the present invention is as follows figure 1 As shown, first determine the accuracy and stability of the standard meter output; if the standard meter meets the requirements, continuously read the power RMS value of the standard meter and the power RMS value of the electric energy meter to be tested; according to the read standard meter power RMS value Calculate the average power RMS value of the standard meter and the average power RMS value of the electric energy meter under test separately from the RMS value of the electric energy meter under test; finally calculate the electric energy meter under test according to the obtained average RMS value of the standard meter and the average power RMS value of the electric energy meter under test Error, and debug the electric ener...

Abstract

The invention relates to an error debugging method for an electronic electric energy meter, and belongs to the technical field of electric energy meter debugging. The error debugging method comprises the steps of firstly judging the accuracy and the stability of a standard meter in output; continuously reading power effective values of the standard meter and power effective values of an electric energy meter to be tested if the standard meter conforms to requirements; respectively calculating an average power effective value of the standard meter and an average power effective value of the electric energy meter to be tested according to the read power effective values of the standard meter and the read power effective values of the electric energy meter to be tested; and finally calculating an error of the electric energy meter to be tested according to the acquired average power effective value of the standard meter and the acquired average power effective value of the electric energy meter to be tested, and carrying out debugging on the electric energy meter to be tested according to the error. According to the invention, the error of the electric energy meter is calculated through a mode of the power effective values, the error calculation time of the electric energy meter is shortened, and the error debugging efficiency is improved. Meanwhile, the invention can also judge the accuracy and the stability of a debugging and detecting platform in output, thereby avoiding a quality problem caused by problems of the debugging and detecting platform.

Description

Technical field [0001] The invention relates to an error debugging method of an electronic electric energy meter, belonging to the technical field of electric energy meter debugging. Background technique [0002] The traditional error debugging method of electronic electric energy meter is to compare the electric energy of the standard meter and the electric energy meter in a certain period of time through the standard meter calibration platform verified by the national agency to calculate the measurement error of the electric energy meter, and the error of the electric energy meter To adjust the coefficient of the electric energy meter to achieve the purpose of accurate measurement. However, this error debugging method is inefficient, especially when debugging a low current gear (less than 5% Ib), it takes a longer time, resulting in high labor costs. Summary of the invention [0003] The purpose of the present invention is to provide an error debugging method of an electronic e...
