摘要

The results of a series of tests conducted on a cross section of commercially available self-contained induction watthour meters are presented. The meters were exposed to electrical interference typical of the application environment, and the effect on accuracy was recorded. An extensive investigation resulted in the setting of interference parameters which could be simulated in the laboratory. These included harmonic frequencies, transient surges, distortion of current waveform and electrical noise. Extensive tests were conducted on five types of meters from four manufacturers. The effect of electrical interference on accuracy is presented. An automatic data acquisition system was developed to allow the recording of this extensive data in an economical way. The test methodology and instrumentation also are described. (ERA citation 07:043295)
