Abstract

trata-se de um sistema detonador em que um detonador está conectado por meio de um chicote elétrico de interior de poço a um barramento que se estende de um controlador de detonação e em que um componente está conectado em série com o chicote elétrico de interior de poço para limitar a corrente de vazamento no chicote elétrico a um nível que pode ser acomodado pelo controlador de detonação.
