This document includes recommended practices for grounding of dc equipment enclosures installed in dctraction power distribution facilities. DC distribution facilities may include, but are not limited to, traction power substations, tie breaker stations, gap breaker stations, section huts, cross-tie substations, circuit breaker houses, and equalizer houses.
Purpose
This document provides recommended practices for grounding dc equipment enclosures to systemdesigners, transit authorities, system operators, and manufacturers of dc traction power distributionfacilities.
Abstract
New IEEE Standard - Active.The grounding of dc equipment enclosures installed in dc traction power distributionfacilities as well as related insulation treatments required for solid and resistance groundingmethods are covered in this standard. Guidelines are also given for material, installation, andtesting of insulation used in dc traction facilities and further recommended criteria for acceptability are provided. System grounding, though related, is not covered in this document
