Abstract

"DISPOSITIVO PARA MEDIçãO DE VOLTAGEM". Um dispositivo para medição de voltagem alternada num condutor sob teste, que compreende um primeiro conjunto de sensores de capacitância (32a-f) montado numa parte de suporte eletricamente isolante. Os sensores ficam dispostos sobre uma parte de suporte em intervalos ao longo de um primeiro círculo idealizado e são conectados em paralelo entre um condutor interno de sinal (33) e um condutor de referência (37) de voltagem zero. Um segundo conjunto de sensores de capacitância (34a-f) é montado na parte de suporte em intervalos ao longo de um segundo círculo idealizado, sendo conectado em paralelo entre um condutor externo de sinal (35) e o condutor de referência (37). A parte de suporte tem configuração de forma a permitir que um condutor sob teste (38) seja introduzido no interior do dispositivo de forma que os sensores envolvam o eixo do condutor. Cada sensor tem um eletrodo de sinal (48), conectado ao condutor de sinal, e um eletrodo de referêncía (50), conectado ao condutor de referência, sendo orientado com o eletrodo de sinal fazendo frente para o condutor sob teste. A voltagem no condutor sob teste é gerada como função de voltagem ao longo do condutor de sinal e do condutor de referência. (figura 3A).
