Abstract

"SISTEMA E MéTODO PARA COMPENSAçãO DIGITAL DE ERROS INDUZIDOS POR FREQüêNCIA E TEMPERATURA EM UM DESLOCAMENTO DE AMPLITUDE E FASE NA DETECçãO DE CORRENTE DE MEDIDORES ELETRôNICOS DE ENERGIA". O deslocamento de fase em um medidor de energia eletrônico é compensado pela obtenção de leituras de temperatura (100) e freqüência (200) no medidor e utilização dessas leituras em um processador de sinal digital (DSP) (14) residindo dentro do medidor de energia eletrônico. A compensação de temperatura e freqüência é realizada para cada calibração de fase e o resultado é armazenado no DSP. Para reduzir a possível influência de ruído no sistema, os valores de DSP compensados são filtrados (120) para proporcionar uma regularização nos dados.
