System for measuring electrical energy of alternating current in secondary electric conductor in electric current transformer station, has time synchronization software synchronizing samples of measured intensity relative to voltage samples

摘要

The system has a primary module (60) comprising determination software (104) to determine transform coefficient of samples of measured voltage and transmitting software (106) to transmit a message (M1) containing the coefficient. Secondary modules (62A-62N) have reconstruction software (121A-121N) to reconstruct samples of the voltage. Calculation software (123A-123N) calculates electrical energy from the samples of voltage and of measured intensity. Time synchronization software (122A-122N) synchronizes the samples of the intensity relative to the reconstructed samples. Independent claims are also included for the following: (1) an electric current transformer station (2) a method for measuring electrical energy of alternating current circulating in a secondary electric conductor.
