Problems solved by technology
The on-site inspection wiring is relatively complicated, and there is a high safety risk in the inspection process. To carry out a large-scale electric energy meter inspection wiring, the investment in equipment and resources is very huge, the safety risk is high, and improvement is urgently needed
[0003] The internal circuits and components of the electric energy meter may be artificially damaged, resulting in inaccurate measurement. Event records such as the opening of the electric energy meter, voltage loss events, and power outage events are helpful to discover the artificial damage to the internal circuits and components of the electric energy meter. However, the event record is not displayed on the display screen of the electric energy meter, so it cannot be paid attention to when carrying out electricity inspection
There is a risk that the energy meter will be vandalized without being discovered, and improvement is urgently needed

Description
technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a hand-held device capable of rapidly displaying electric phasor diagrams of internal components of an electric energy meter. Background technique [0002] The energy meter is a measuring instrument for the trade settlement between the power company and the electricity customer. It is very important that the wiring of the electric energy meter is correct, and if the wiring is wrong, it cannot be measured correctly. There are more than 750 kinds of incorrect wiring combinations of electric energy meters. Due to factors such as personnel skill level and equipment, it is often found that electric energy meters with incorrect wiring are running in the power industry. At present, it is found that the wiring error of the electric energy meter is mainly completed by the field calibrator of the electric energy meter, and the wiring inspection needs to be c...
