Abstract

SISTEMA DE MONITORAçãO EM TEMPO REAL DO ESTADO DE BUCHAS CAPACITIVAS DE TRANSFORMADORES DE POTêNCIA, REATORES DE POTENCIA, TRANSFORMADORES DE CORRENTE, DISJUNTORES E CONGêNERES. Se aplica preferencíalmente a transformadores de potência; reatores de potência; transformadores de corrente, disjuntores e congêneres, sendo um sistema passível de realizar a monítoração em tempo real de buchas capacitivas (1), cada uma provida de um "tap" capacitivo ao qual se conecta um adaptador de "tap" (3) que, por sua vez se conecta a um módulo de medição (4) que recebe sinais provenientes do "tap" capacitivo (2) de três buchas (1) que formam um conjunto trífásíco. Um ou mais módulos de medição (4) podem se conectar a um único módulo de mterface homem-máquina (5), por meio de uma comunicação serial (6), formando um sistema modular.
