Abstract

CABO TRANSMISSOR PARA UTILIZAçãO EM LEVANTAMENTO ELETROMAGNéTICO E SISTEMA DE LEVANTAMENTO ELETROMAGNéTICO Trata-se da provisão de múltipas fontes para um cabo transmissor para utilização em operações de levantamento eletromagnético. O cabo transmissor inclui uma antena de dipolo compreendendo um par de eletrodos afastados entre si montados em seus respectivos cabos. Duas antenas podem ser alimentadas com energia a partir de cada fonte. Alternativamente, as saídas de cada fonte são ligadas a um par comum de antenas. Uma única fonte de alimentação de grande porte pode ser montada em uma embarcação para fornecimento de energia através do cabo de reboque. Alternativamente, várias fontes de alimentação podem ser providas a bordo da embarcação, com cada fonte de alimentação possuindo condutores dedicados dispostos através do cabo de reboque para alimentação de energia à pluralidade de fontes corrente.
