Combat Casualty Simulation on Shipboard Electrical Power Systems (Active Demonstration)

Abstract

For many years, electrical cable exposed to fragmentation was never taken into consideration in fault predictions for electrical power distribution systems. Testing, which began in 1990 by NSWC Annapolis under the Electrical Power Survivability Program, to evaluate the effects of combat casualty on electrical power distribution systems, verified that a condition of multiple simultaneous faults could occur from typical weapons threats. Four phases of testing were performed to characterize damage to electrical power cables. These four testing phases were severing a single energized power cable, fragmenting multiple power cables fed from a single source and fragmenting multiple power cables fed from multiple sources. This paper reviews the various phases of testing conducted from the inception of the program and the test results.
