Abstract :
A new versatile digital system for high accuracy electrical power measurements has been implemented in order to establish the new Spanish electrical power standard for non sinusoidal conditions. The system can be arranged in the most used configurations in other standards. A description of these configurations and a comparison of them are given. The results of a comparison between the most advantageous configuration and the current Spanish power standard in sinusoidal conditions are also presented.
