Revision Standard – Inactive – Superseded. Superseded by 1050-2005 Information about grounding methods for generating station instrumentation and control (I & C) equipment is provided. The identification of I & C equipment methods to achieve both a suitable level of protection for personnel and equipment is included, as well as suitable noise immunity for signal ground references in generating stations. Both ideal thoretical methods and accepted practices in the electric utility industry are presented.
