Abstract

SISTEMA E MÉTODO DE MONITORAMENTO DE FORNALHA A ARCO ELÉTRICO. Um sistema e método são descritos para monitorar os parâmetros operacionais de uma fornalha a arco elétrico (16) tendo um circuito elétrico primário (14) compreendendo um transformador de corrente primária (52) . O método compreende monitorar o transformador de corrente primária da fornalha, coletar dados a partir desse, transmitir os dados coletados a um servidor (18) tendo um monitor conectado de forma operativa, e exibir os dados coletados no monitor em tempo substancialmente real. O servidor também coleta informação sobre a performance da fornalha a partir de um computador de lógica programável e informação inserida manualmente por um operador em um sistema visualizador de monitoramento de fornalha (72), que pode também ser exibido em tempo substancialmente real no monitor.
