Grounding practices that have generally been accepted by the electric utility industry as contributing to effective grounding systems for personnel safety and equipment protection in generating stations are identified. A guide for the design of generating station grounding systems and for grounding practices applied to generating station indoor and outdoor structures and equipment, including the interconnection of the station and substation grounding systems, is provided.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.

IEEE Guide for Protection, Interlocking, and Control of Fossil-Fueled Unit-Connected Steam Stations
Information regarding the essential subsystems that make up a fossil-fueled unit-connected boiler-turbine-generator (BTG) station is presented. Typical interlocking, control, and protection for operating the subsystems in a coordinated order to ensure proper startup and safe shutdown are described. The primary purpose is to provide a basis for qualitative evaluation of overall design of a unit-connected fossil-fuel plant, and for writing general operating guides of an educational nature to aid in acquainting personnel with boiler-turbine-generator systems.
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
