The elimination of motor-generator sets as transient buffers for SAGE computers

Motor-generator sets are frequently used as buffers to isolate electronic equipment from severe power transients which may cause misoperation. An investigation of voltage tolerances for digital computers, performance of d-c supplies, and probabilities of fault occurrences indicates that if the power is generated on the site of the electronic equipment, motor-generator sets are not necessary to meet the critical requirements of the digital computers employed in the SAGE (Semi-Automatic Ground Environment) air-defense system.
