Abstract

The present invention provides a traceability verification method of a network electric energy meter. The method is used for a network electric energy meter formed by an electric energy meter, a negative control terminal and a main station, and the electric energy meter is connected to a power grid through a voltage transformer and a current transformer. The method comprises a step of setting a standard electrical energy meter in a field, connecting the standard electrical energy meter between the electric energy meter and the current transformer to obtain the current signal of the power grid, and connecting voltage interfaces of the standard electrical energy meter and the electric energy meter to realize electric conduction to obtain the voltage signal of the power grid, and a step of reading an electric energy metering result formed by the standard electrical energy meter according to the current signal and the voltage signal, and comparing the read metering result and the electric energy result of the main station to realize the verification of the network electric energy meter. By applying the method, in the condition of not influencing the normal working of the network electric energy meter, equipment is directly carried to the installation site of the negative control terminal (or an electric energy meter) in the network electric energy meter, and the verification of the metering performance can be realized.

Description

technical field [0001] The invention relates to the technical field of verification of networked measuring instruments, in particular to a traceability verification method of a networked electric energy meter. Background technique [0002] Networked measuring instruments refer to the organic collection of all software and hardware that can help people obtain measurement data or information at any time and place, and the networked energy meters used in the field of electrical engineering are typical networked measuring instruments. [0003] The networked electric energy meter is formed by the electric energy meter, the load control terminal and the master station. The network uploads the above-mentioned collected signals to the main station for analysis and judgment on the operation of the on-site electric energy meter, and realizes real-time monitoring of the operating state of the electric energy meter, such as whether the electric energy metering is accurate, whether the w...
