Abstract

"CONJUNTO DE MEDIçãO DE INTERIOR DE FURO". Um conjunto de medição de interior de furo compreendendo um invólucro metálico alojando uma pluralidade de seções de ferramentas, uma das quais inclui um detector sensível a um campo magnético, e um suprimento de corrente contínua (CC) para as mencionadas seções de ferramenta, o suprimento de energia elétrica e as seções de ferramenta sendo eletricamente conectados ao invólucro, caracterizado pelo fato de que o suprimento de energia e conectado a pelo menos uma seção de ferramenta via um circuito de comutação e um arranjo condutor, o circuito de comutação compreendendo um capacitor, uma pluralidade de comutadores e meios de controle operacionais para, alternadamente, carregar o capacitor pelo suprimento de CC e descarregar o capacitor através da mencionada pelo menos uma seção de ferramenta usando o arranjo condutor de modo a inibir a geração de um campo eletro-magnético no arranjo condutor entre o capacitor e a mencionada pelo menos uma ferramenta.
