Safety-Margin Measurements of Electroexplosives: DC-RF Power-Substitution Method

Some of the indirect methods in current use for measuring the safety margins of installed electroexplosives are briefly reviewed. The basic requirements of the military specifications are indicated. A direct measurement of resistance variation versus dissipated power, on actual devices, is proposed as a better alternative. The method provides the capability of measuring unmodified real electroexplosives with some temperature coefficient, and also indicates a new utilization of SEM fuses and deactivated EED´s for quantitative measurements.
