FRACTIONAL SAMPLING OF ELECTRICAL ENERGY |
摘要 |
A novel method and device for measuring electrical parameters in an energy meter in an electrical system is described. The novel method samples an electrical energy signal and determines a relevant portion of the sampled electrical energy signal. The relevant portion of the electrical energy signal is then separately multiplied by a first and second reference waveform. The relevant portion may be reflective of a particular line cycle at a particular frequency of interest. In addition, other samples in the line cycle may be accumulated. The samples whose portions may be determined may be the first and/or last signal, while other sampled signals may be evaluated in whole.
