Abstract

CIRCUITO ELETRÈNICO DE DETECçãO DE ADULTERAçãO PARA UM MEDIDOR DE ELETRICIDADE. Um sistema e método de detecção de adulteração de medidor de eletricidade para detectar a remoção de um medidor de um encaixe de medidor e gerar um sinal de adulteração quando tal remoção for detectada. O circuito de detecção de adulteração inclui uma unidade de controle que possui um dispositivo de armazenamento de energia que é carregado durante a operação normal do medidor de eletricidade. Quando a energia é interrompida ao medidor de eletricidade, a unidade de controle aplica uma voltagem de carregamento a um dispositivo de regulagem de voltagem dentro do medidor de eletricidade, O dispositivo de regulagem de voltagem pode ser carregado apenas quando o medidor de eletricidade estiver instalado dentro do encaixe de medidor. Após aplicação da voltagem de carregamento ao dispositivo de regulagem de voltagem, a unidade de controle percebe se o dispositivo de regulagem de voltagem foi carregado. Se o dispositivo de regulagem de voltagem não tiver sido carregado, a unidade de controle indica que o medidor de eletricidade foi removido do encaixe de medidor.
