Abstract:

The response of a typical field army electrical power system to the electromagnetic pulse was measured at sufficient distance from ground zero to prevent damage from blast and thermal effects. Twenty channels of a recording oscillograph were used to monitor selected variables from -15 seconds to 5 seconds and to provide fiducial indications. From analysis of the data, it was determined that the electrical power system was shut down by a combination of effects such as prompt radiation and effects of the electromag netic pulse. A failure mechanism theory was postulated. Laboratory investigation verified the basic theory. Further laboratory investigation, analog computer analysis, and transient circuit analysis were conducted to determine the charac teristics of the current pulse introduced by the power cable necessary to result in the failure mechanism. If induced currents in the distribu tion cable were the only cause of power system shutdown, a current pulse of approximately 3570 amps maximum would be required. Author
