An Overview of Computer Power for JSC Facilities
MetadataShow full item record
Techniques and devices used by the National Aeronautics and Space Administration (NASA) at the Johnson Space Center (JSC) to provide and maintain a quality power distribution system are discussed. Quality power is essential to support the array of facilities and functions involved in planning, developing, testing, and controlling a major portion of this nation's space exploration program. An overview is provided of the distribution system and components. Discussions address the criticality of the complex and computers in particular, the disturbance immunity of the hardware, and the redundancy of the systems. No attempt is made to draw absolute comparisons between the various types of power conditioners and their derivatives on the market today. Rather, an explanation is given of the rationale used at JSC to select the equipment and the circuit configurations that have proven to provide the required power quality and reliability. Because that level of power quality is sustained only through well planned and executed operation and maintenance activities, a description of JSC's program is also given.
