【 摘 要 】

The paper presents a method for evaluating the accuracy of indications of the direct current Watt-hour meters in a designed and constructed measuring system. Such measuring system is composed of two multi-function calibrators, and a specialised high-voltage attachment dedicated for this system, which makes it possible to generate direct voltages in a required range up to 4 kV with a suitably high precision. The authors described in detail particular elements of the measuring system together with the results of its calibration. They showed the results of experiments carried out on a large and representative number of LE3000plus Watt-hour meter items.
