This report evaluates the feasibility of isolating vulnerable equipment of the electric power system from sources of electro-magnetic pulses EMP through the use of supervisory control and dispatched personnel to perform remote and manual switching, respectively, in distribution substations. The data contained in this report were obtained primarily through interviews of electric utility personnel. The conclusion drawn from these data is that it is possible to isolate a significant portion of the vulnerable equipment in the distribution system from sources of EMP. This would not only reduce the number of failures of equipment in the distribution system and hence system faults, but would also configure the system in a more secure state with respect to electromechanical stability. Problems associated with the transition from the normal system state to the new operating state and the restoration of service to loads after the attach are discussed. The report also contains information on the development of a new lightning arrester design that has better EMP characteristics than existing designs.
