Application of and rating structure for ground and test devices used in metal-clad switchgear

摘要

Ground and test devices are accessories for use in grounding and testing the primary conductors in metal-clad switchgear. The types commonly available and their use are described. It is noted that these devices are not covered by any existing standards. Rating structures and test requirements that should apply to these devices are examined, and a proposal is made for the creation of a standard to cover ground and test devices.
