Abstract

"MEDIDOR PARA MEDIR A ENERGIA ELéTRICA". A presente invenção refere-se ao campo de medidores de energia elétrica utilizando processamento de sinais digitais de maneira a oferecer o consumo de energia elétrica pela integração da dita energia elétrica. O dito medidor (1) compreende um sensor de tensão (4) de maneira a gerar um sinal de tensão analógico responsivo a uma tensão fornecida à dita carga, um sensor de corrente (3) de maneira a gerar um sinal de corrente analógico responsivo a uma corrente fornecida à dita carga, um conversor analógico/digital (8) incluindo primeiros dispositivos de amostragem para gerar uma primeira amostra de tensão baseada no dito sinal de tensão analógico em um primeiro tempo de amostragem e segundos dispositivos de amostragem para gerar uma primeira amostra de corrente baseada sobre o dito sinal de corrente analógico em um segundo tempo de amostragem. O medidor ainda compreende dispositivos de compensação de fase (9) para compensar comutações de fase entre os ditos sinais de tensão e de corrente analógicos ao ajustar o dito segundo tempo de amostragem comparado com o dito primeiro tempo de amostragem de maneira a fornecer a dita primeira amostra de tensão e a dita primeira amostra de corrente substancialmente em fase, dispositivos (6, 12 e 13) para saturar os ditos sinais analógicos de tensão e corrente de maneira a produzir ondas de tensão e corrente substancialmente quadradas e dispositivos (15) para avaliar o dito deslocamento de tempo de amostragem ao tomar as diferenças entre o tempo de cruzamento zero da dita onda quadrada de corrente e o tempo de cruzamento zero da dita onda quadrada de tensão.
