Abstract
Systems and methods may maintain protection of electric power delivery systems in the event of an attack on protection and/or control features of the power system. Primary protective functions may be physically isolated from other functions in primary protection relays. Integrators may facilitate non-primary protection functions and disconnect all communication with primary protection relays in the event of an attack. Primary protection relays maintain protection functions even during the attack or unavailability of the integrators.
