Minimum Efficiency Values for Liquid-Filled Distribution Transformers
1. Scope
1.1
This Standard specifies energy efficiencies for liquid-filled distribution transformers. The Total Ownership Cost(TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric
utilities. This Standard also specifies an optimal method for nonutility users, based on a modified TOC methodology that meets the conditions of energy…

Information technology - High-Performance Parallel Interface - Part 2: Framing Protocol (HIPPI-FP)
This standard defines the data framing for an efficient simplex high-performance point-to-point interface. Characteristics of HIPPI-FP include: - large block data transfers with framing to split the data into smaller bursts; - separation of user control and data information, and early delivery of the control information; - identifiers for multiple upper-layer protocols (ULPs); - support for…
Graphical symbols for use on equipment - Part 1: Overview and application
Contains a presentation of the graphical symbols with the corresponding descriptions in numerical order which does not necessarily represent any functional grouping. It is complemented by an alphabetical index and a graphical survey of the symbols. Additional information is provided to the user by classifications to form and function, and the examples of application. IEC 60417-1 and 60417-2…
