This document includes recommended practices for grounding of dc equipment enclosures installed in dc traction 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.
This guide specifies a method of synchronous monitoring, the principle of siting, the technical requirements of the monitoring device and system, and a method of data processing for stray current in urban rail transit’s direct current (dc) traction system and dc bias current in the power grid.
