EM Susceptibility Studies and Measurements on Electro Explosive Devices

Abstract

E lec tro-exp los ive d ev ices (EEDs) a re widely used in ground b ased , ship borne and air borne sy s te m s as a c tu a ­ t o r s . The EMI suscep t ib i l i ty s tud ies on EEDs and t h e i r fu n c t io n a l a s se ssm en t in an EM e nv ironm en t a re most im p o r t a n t when EEDs a re used as i n i t i a to r s of c e r ta in explos ives/am munit ions. P re m a tu re ex c i t a t io n of such dev ices may cause pe rsonne l haza rds or mission fa i lu re s in c r i t i c a l moments and a t t im e s , EEDs may exper ience dudding due t o exposure to high EM fie lds .
