KSC-STD-E-0022

Abstract

This standard provides design and testing requirements for bonding, grounding, shielding, electromagnetic interference (EMI), lightning protection, electrostatic discharge (ESD) protection, transient protection, and surge suppression for electrical and electronic ground systems (GS) to be used at the Kennedy Space Center (KSC). It governs both fixed and portable GS consisting of ground support equipment (GSE), ground support systems (GSS), and operational communications systems that are used in processing, launch, landing, and retrieval sites. This GS standard further defines requirements in KSC-DE-512-SM, Facility Systems, Ground Support Systems and Ground Support Equipment General Design Requirements, KSC-E-165, Electrical Ground Support Equipment Fabrication, Specification for, KSC-E-166, Installation and Assembly, Electrical Ground Support Equipment (GSE), Specification for, and KSC-GP-864, Vol. IIA, Electrical Ground Support Equipment Cable Handbook, This standard is used in conjunction with the KSC facility standard KSC-STD-E-0012, Facility Grounding and Lightning Protection, Standard for, which provides requirements for facility grounding, bonding and lightning designs. These facility systems provide connections and paths to earth ground for GS through certified ground plates that provide low-impedance paths to the local counterpoise grounds. <br>Commercial, military, and other government standards are cited where they provide acceptable design requirements for ground systems used at KSC. Where these standards lack sufficient design requirements and testing for KSC ground systems, KSC-developed requirements are provided and the source(s) identified at the end of the requirement statement. Guidance statements that follow the stated requirements are italicized. <br>This standard, together with KSC-STD-E-0012, creates a comprehensive set of requirements for protecting KSC ground systems from expected electrical disturbances.
