The presentation was made at IEEE PES 2011 General Meeting Super Sessions in July, 2011, and describes how Aurora was defined as a gap in protection which has the following characteristics: 1) Out-of-synch, open/close sequence of 1 or more breakers; 2) Induced torques can cause permanent damage to the generator; 3) Open/close as fast as 10 to 15 cycle, i.e., traditional protection will not trip (gap); 4) Physical/Cyber attack.
