Susceptibility of bridgewire EED (inert) against HPEM

A basic disadvantage of electro-explosive-devices (EED) is that they function as a direct result of an input of electrical energy, which causes the surrounding explosives of the heating element to react. Therefore, electromagnetic interferences (EMI) could initiate an EED directly or indirectly by upsetting the connected firing circuit. This paper investigates the application of an infrared radiation thermometer within a pulsed HPEM-environment in order to measure induced EED energy. The results are compared with direct EED current and voltage measurements.
