High Explosive Field Test of Hardened Electrical Generators
Abstract
Emergency electrical power for hardened Naval installations is often provided by diesel engine driven generator sets. In a continuing effort to determine the degree of protection required to provide continuous electrical power in an air blast environment, NCEL participated in Event DIAL PACK, the detonation of a 500-ton, surface-tangent spherical charge of TNT at the Canadian Defence Research Establishment, Suffield, Alberta, Canada in July 1970. Two 10 kw diesel generator sets were preferentially hardened, placed in grate-covered pits and subjected to a 100 psi overpressure environment. Minor damage to grate pit covers and generator accessory equipment was incurred, but both generator sets continued to produce electrical power during and after the blast. The test showed that minimal hardening of the sensitive generator components will enable them to operate successfully in a 100 psi environment.
