Test device of the impedance of a power line and its application to the test of primers means pyrochniques

摘要

This device makes it possible to be tested at least one power line comprising an electric load connected to a power stage capable of supplying it with a nominal current high. It comprises: - means of a constant current generator 205 and 207 are able to circulate in the line li, a test current im of low value with respect to the nominal current, - an electric dipole d 1 connected in the power line and able to generate a constant voltage shift carrying the power stage 10i to saturation when the load r.sub.ci is traversed by the current of the test, - of the measuring means 206 and 208 of the voltage drop across the terminals of the power line, and - means 209 - 213 of the operation of the result of said measurement of voltage. / p & & p & application to the test of the beginnings of pyrotechnic means for electrical firing.
