Abstract

A method for debugging a three-phase power energy meter comprises the following steps: reading the power Ps (s stands for a standard meter) of each phase from the standard meter and the corresponding power Pm (m stands for the power energy meter) from the three-phase power energy meter respectively; calculating the error value based on (Ps-Pm)/Ps; and then, adjusting the error of the three-phase power energy meter through the error value, wherein the method can adjust the error of each phase of the three-phase power meter. The method reduces the artificial error and improves the efficiency.

Description

Method for debugging three-phase electrical energy meter

Technical field

The present invention relates to a kind of adjustment method of electric energy meter, especially the adjustment method of three-phase electric energy meter.

Background technology

At present, the adjustment method of three-phase electric energy meter mainly is to adopt the error input method.The error amount that this method need show the verification stage body by the manual method input after, electric energy meter is proofreaied and correct, and can only be during debugging by adjusting mutually, not only time-consuming but also be easy to generate mistake, efficient is low.

Summary of the invention

The objective of the invention is for provide a kind of can be from the adjustment method of normal moveout correction three-phase electric energy meter error, it has overcome the shortcoming of existing method for debugging three-phase electrical energy meter.

The object of the present invention is achieved like this: computing machine reads the power P of each phase respectively from standard scale MarkWith corresponding power P mutually on the three-phase electric energy meter Table, and according to (P Mark-P Table)/P MarkCalculate error amount, by above-mentioned error amount the three-phase electric energy Watch Error is adjusted again.

Above-mentioned adjustment method can be adjusted the error of each phase of three-phase electric energy meter simultaneously.

The invention has the beneficial effects as follows the minimizing mistake, improve and produce debugging efficiency.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is the adjustment method synoptic diagram of former three-phase electric energy meter.

Fig. 2 is an adjustment method synoptic diagram of the present invention.

Embodiment

The technical solution adopted in the present invention is: as shown in Figure 2, computing machine reads the power P of each phase respectively from standard scale Mark, with corresponding power P mutually on the three-phase electric energy meter Table, and according to (P Mark-P Table)/P MarkCalculate error amount, by this error amount the three-phase electric energy Watch Error is adjusted again.The correctness of reading numerical values in order to guarantee, computing machine adopt the method for the value of making even when reading of data.This adjustment method can also can be debugged each phase error of three-phase electric energy meter simultaneously to the three-phase electric energy Watch Error by debugging mutually.

Compare with former adjustment method shown in Figure 1, the present invention has realized the debugging robotization, has reduced personal error, has improved the efficient of three-phase electric energy meter debugging.
