Abstract

a invenção refere-se a uma combinação de um condutor, como um barramento, e um dispositivo para medir a tensão em corrente alternada no condutor, cujo dispositivo compreende: - uma camada de isolamento disposta no condutor; - uma placa de capacitor disposta na camada de isolamento para posicionar a placa do capacitor a uma distância fixa do condutor para formar um primeiro capacitor; - um segundo capacitor disposto eletricamente entre a placa do capacitor e o solo para fornecer um divisor de tensão capacitivo com o primeiro capacitor; e - meios para medir a tensão na placa do capacitor, - meios para medir a frequência da tensão no condutor; e - meios para calcular a tensão em corrente alternada no condutor com base nas capacidades do primeiro e segundo capacitores, a tensão medida, a temperatura da camada de isolação medida e a frequência medida.
