Abstract
"SISTEMA E MéTODO PARA AQUISIçãO DE VOLTAGENS E MEDIçãO DE VOLTAGEM EM UM SERVIçO ELéTRICO USANDO UM TRANSFORMADOR DE CORRENTE NãO ATIVO". Um circuito de aquisição de voltagem para a detecção de sinais de voltagem de entrada em cada fase de um serviço elétrico inclui uma configuração de transformador de corrente não ativo que é operável por uma ampla faixa de voltagem de entrada. A configuração de transformador de corrente inclui enrolamentos primário e secundário, um resistor de entrada e um resistor de carga através do que uma voltagem de saída é definida. o resistor de entrada pode ser relativamente grande, tal como da ordem de um M<87>, e o núcleo de transformador pode ter um núcleo nanocristalino caracterizado por propriedades magnéticas previsíveis versus níveis de fluxo de transformador variados. Esta previsibilidade operacional facilita uma compensação de fase através de filtração digital ou, de outra forma, para qualquer deslocamento de fase induzido entre as voltagens de entrada e de saída do transformador de corrente. Os circuitos de aquisição de voltagem em questão podem ser providos para a detecção de cada fase de um serviço elétrico de fase única ou multifásico, por meio do que as voltagens detectadas são subseqüentemente providas para componentes adicionais de um medidor de eletricidade, tais como componentes de suprimento de potência e outros de processamento, incluindo um conversor de A/D e um microprocessador para a determinação de quantidades de energia.
