Abstract
"ELEMENTO DE SOBRE-CORRENTE INSTANTâNEO PARA USO EM LTM RELé PROTETOR BASEADO EM MICROPROCESSADOR PARA UM SISTEMA DE POTêNCIA". O elemento de sobre-corrente instantâneo, usado em um relé protetor baseado em microprocessador para um sistema de potência, inclui um filtro de resposta a impulso finita, que é geralmente um filtro de cosseno e é responsivo à forma de onda de corrente do transformador de corrente para determinação de falha a menos que a distorção na corrente alcance um limiar pré-selecionado, a qual ponto um circuito de detector de pico é usado para prover os valores de magnitude de corrente para a determinação de falha. O valor de RMS de circuito (88) é comparado contra o valor de limiar em comparador (90).
