Abstract (en)
This device makes it possible to test at least one power line comprising an electrical charge connected to a power stage capable of feeding it with a high nominal direct current. It comprises: - direct-current generating means (205, 207) capable of circulating in said line (Li) a test direct current (Im) of low value in relation to the nominal current, - an electrical dipole (Di) connected in said power line and capable of generating a constant offset voltage bringing the power stage (10i) to saturation when the test direct current passes through the charge (Rci), - means (206, 208) for measuring the voltage drop at the terminals of the power line, and - means (209-213) for processing the result of said voltage measurement. The invention is used for testing the primers of electrically ignited pyrotechnic means. <IMAGE>
