About This Item
22-1925 is the AIEE Standards document for disconnecting and horn gap switches, giving technical direction for equipment used in power, energy, and industrial applications. It is relevant to the design and application of switching devices where visible isolation, interruption characteristics, and dependable operation matter. As a superseded English-language standard, 22-1925 remains useful for understanding the historical requirements and terminology associated with these switch types in electrical systems.
What is 22-1925?
22-1925 sets out the standards context for disconnecting and horn gap switches associated with AIEE practice. The document addresses a class of switching equipment used to isolate circuits and manage electrical separation in systems that may involve higher-voltage service or industrial distribution arrangements. For engineers, purchasers, and archivists, this technical document helps define how such switches were classified, specified, and evaluated in its era. The standard number 22 identifies the broader series, while 22-1925 is the specific item within it.
Where is 22-1925 used?
This standard is most relevant in power and energy installations, utility equipment records, and industrial electrical systems where disconnecting or horn gap switches were part of the switching scheme. It may be used when reviewing legacy substations, maintenance documentation, or historical procurement files tied to circuit isolation and visible break devices. 22-1925 also supports technical reference work in components, circuits, devices, and systems applications where older switching practices still need to be understood accurately.
Why is 22-1925 important?
22-1925 matters because standards for disconnecting and horn gap switches help bring consistency to design expectations, ratings, and operating practice. In practical terms, that supports safer isolation, clearer procurement requirements, and more reliable comparison of equipment across projects or eras. For legacy systems, the document can also reduce ambiguity during inspection or replacement planning. Using 22-1925 as a reference helps preserve technical alignment when evaluating older switchgear-related components and their intended performance.
