数字化电能表较电子式电能表计量及检测差异性研究
Research on measurement and detection difference of digital input electricity meter compared with electronic watt-hour meter
Compared with the electronic watt-hour meter, the digital input electricity meter hardware structure is greatly simplified, and the measurement performance has obvious differences. The digital input electricity meter detected by the national standard still has large errors and long-term mismeasurement phenomenon in the field, indicating that the existing detection items and test methods have some deficiencies.In order to ensure the accuracy and reliability of digital input electricity meter field operation, this article starts from working principle of the digital input electricity meter, on the basis of the existing test specification, targeted put forward the detection items and test method, through the test and field running show that the proposed test items can effectively used to evaluate digital input electricity meter measuring performance, provide a reference for digital input electricity meter testing, has a certain practical significance.
