Embodiment 1

[0026] The invention of this example provides a load record test method for electric energy meters, which includes summarizing the load record test into four steps by changing the load record mode word, the load record interval time, and optimizing the combination of integrated test items.

[0027] The most recent load record block of the first test: "voltage, current, frequency", "active and reactive power", "power factor", "active and reactive total energy", "I and II quadrant total reactive energy", " "Current demand" and can be set within the range of 1 to 60 minutes. The interval time of each type of load record can be the same or different; the second test is the latest load record block: "voltage, current, frequency", "active, reactive Power", "power factor", "active and reactive total electric energy", "ⅢⅣquadrant reactive total electric energy", "current demand" and can be set within the range of 1 to 60min, the interval time of each type of load recording can be The ...

Abstract

The invention relates to an electric energy meter load record test method. The method comprises the steps of testing of load record blocks, testing of load record blocks of given time, and testing of the data of storage space of load records. According to the technical solution, the requirements for the electric energy meter load record function in the power industry standards are subdivided into steps for measurement, and the relationships between the standards are analyzed profoundly to create a scientific and reasonable test method. The technical solution shortens the test time of load record tests, guarantees the function fulfilling quality, prevents errors caused by human factors and increases the test efficiency.

Description

Technical field: [0001] The invention relates to the field of electric power metering, and more specifically relates to a load recording and testing method of an electric energy meter. Background technique: [0002] Functional testing is an important link to ensure the accuracy of smart energy meters. Its content covers a wide range, including modules such as metering function, event record, alarm function, and fee control encryption. In the full performance testing of smart energy meters, functional testing takes up 20% of the entire testing time due to its complexity and diversity. The load recording function can monitor the working condition of the smart energy meter in real time and record and save it in time, providing important information basis for data monitoring, fault analysis, and power replenishment. [0003] The existing technical solution is to carry out various functions one by one according to the technical requirements, and the test time is relatively long...
