Abstract :
The paper describes methods and results for precision testing of standard energy meters. Several meters were tested in different harmonic condition with various types of electronic load. Linear load, phase fired control load and switched-mode load were used. Results of testing were evaluated and displayed in graph and tables. The proposal of standard testing methodology is described in conclusion.
