Technical Field

Background
In the field of electric energy meters (also called electric energy meters), the measurement error of the electric energy meter is an important index for measuring the performance of the electric energy meter, and is also a key index which is required to be detected again when relevant departments check and accept the electric energy meter.
Before the electric energy meter leaves a factory, when the metering error of the electric energy meter needs to be detected, the error point values such as voltage, current, power factor, error limit and the like are generally tested, and then the data are compared with a standard value to judge whether the error of the electric energy meter to be detected meets the requirement.
Then, in the process of detecting the metering error of the electric energy meter, since there are many error points to be detected, even all the error points need to be detected, which will reduce the production efficiency of the electric energy meter. Of course, in the actual error detection process of the electric energy meter, three typical error points such as the basic current, the maximum current and the minimum electric quantity can be selected for detection, so as to detect whether the overall error is within the range required by the specification.
However, the error point of the minimum current consumes a long detection time, so that although the requirement of error detection is met, the production efficiency of the electric energy meter is reduced because a large amount of detection time is occupied.
