Title
(EN) VALIDATING FUNDAMENTAL-ONLY ENERGY MEASUREMENT
(FR) VALIDATION D'UNE MESURE D'ÉNERGIE D'UNE COMPOSANTE FONDAMENTALE UNIQUEMENT
Abstract
(EN)
Certain aspects and features include a system and method for validating fundamental-only power measurements. A meter testing application calculates an expected registration for a meter under test by comparing a fundamental demand indicating an amount of power expected to be delivered by the fundamental component to a known load with a wideband demand indicating an amount of power expected to be delivered by the wideband voltage to the known load. The application further measures, from the meter under test, a measured registration by applying the wideband voltage component and the known load to the meter under test, which is configured to measure power consumption from the fundamental component only. The application calculates based on the expected registration and the measured registration, an error for the meter. When the error is outside a tolerance, the application identifies the meter under test as non-compliant.

Selon certains aspects et caractéristiques, l'invention concerne un système et un procédé de validation de mesures de puissance d'une composante fondamentale uniquement. Une application d'essai de compteur calcule un enregistrement attendu pour un compteur à l'essai par comparaison d'une demande fondamentale indiquant une quantité de puissance attendue devant être fournie par la composante fondamentale à une charge connue à une demande à large bande indiquant une quantité d'énergie attendue devant être fournie par la tension à large bande à la charge connue. L'application mesure en outre, à partir du compteur à l'essai, un enregistrement mesuré par application de la composante de tension à large bande et de la charge connue au compteur à l'essai, qui est conçu pour mesurer la consommation d'énergie de la composante fondamentale uniquement. L'application calcule, sur la base de l'enregistrement attendu et de l'enregistrement mesuré, une erreur pour le compteur. Lorsque l'erreur se trouve en dehors d'une tolérance, l'application identifie le compteur à l'essai comme non conforme.
