The embodiment of the invention provides an electric energy meter for detecting metering errors. The electric energy meter for detecting the metering errors comprises a metering chip, a controller andone or more signal detecting modules, all the signal detecting modules are connected with the metering chip and used for obtaining the input value and the output value of error detecting signals andtransmitting the input value and the output value of the error detecting signals to the metering chip, and the metering chip is connected with the controller and used for obtaining the attenuation conditions of the error detecting signals according to the input value and the output value of the error detecting signals. The metering errors of the electric energy meter are obtained by the controlleraccording to the attenuation conditions of the error detecting signals, thus the error conditions of the electric energy meter can be judged without the need that the meter is dismounted and re-detected, the replacing cost of the electric energy meter is reduced, and the service life of the electric energy meter is prolonged.
Description
technical field [0001] The invention relates to the technical field of electric energy measurement, in particular to an electric energy meter for detecting measurement errors. Background technique [0002] With the rapid development of smart meter technology, the data management of smart meters is becoming more and more mature, but the management of the operating error data of the electric energy meter is still in a blank stage. As the key data in the operation process of the electric energy meter, the error of the electric energy meter is related to The accuracy of electric energy measurement is the core of the entire electric energy management. However, after the traditional smart energy meter is installed on site, it is impossible to know its own operating error. Due to the difficulty of on-site error detection, the error status of the current energy meter must be dismantled and re-tested. The workload is huge and the energy is increased. The replacement cost of the mete...
