Abstract : The study assesses the damage caused by EMP to relays and other equipment forming the supervisory control circuits of a power system. Electromechanical relays are nearly impervious to damage and false operation due to EMP. Semiconductor relays are expected to be quite sensitive to both. Countermeasures are proposed to limit damage and prevent false operation of supervisory control circuits. (Author)
