The electromagnetic pulse EMP, one of the effects of the detonation of a nuclear weapon, consists of a transient wave of intense electric and magnetic fields. These intense fields can cause malfunction or damage to electrical and electronic equipment exposed to EMP. Such malfunction and damage may be widespread if the detonation is at high altitude. In the report are given the results of an investigation of EMP on an electric power distribution system. Only the power circuitry and power components have been considered in this study. The study is based on numerical and analytical calculations, on discussions with distribution company engineers and power-equipment manufacturer engineers, and on experimental work and field trips. Currents and voltages induced by EMP on distribution circuits as well as those reaching the consumer have been calculated. A comparison with lightning pulses has been made, and the protection presently used against lightning has been explored. Author Modified Abstract
