About This Item
27-1942 is a superseded standard titled AIEE Standards for Switchgear Assemblies, offering technical guidance for power system switching equipment and related assemblies. It is relevant to engineers and buyers looking for historical requirements that shaped switchgear design, arrangement, and performance expectations in power, energy, and industrial applications. As a referenced technical document, 27-1942 can help support comparison, legacy equipment review, and understanding of earlier switchgear practices.
27-1942 overview
This standard focuses on AIEE switchgear assemblies used in electrical power distribution and control. In practical terms, it would have addressed how assemblies were organized, evaluated, and applied in systems where switching, isolation, protection, and control are essential. For users working with legacy drawings, specifications, or archived procurement records, 27-1942 provides a clearer view of the technical basis behind older switchgear requirements and terminology.
Typical use cases
The document is most useful when reviewing or comparing switchgear assemblies in power stations, substations, and industrial electrical rooms. It may also support maintenance teams handling older installed equipment, engineering groups tracing design intent in historical documentation, and procurement staff verifying legacy specification language. Because the subject covers components, circuits, devices, and systems, the standard is especially relevant where coordinated switching and protection functions must be understood in context.
Why this standard matters
Even as a superseded reference, this standard matters because switchgear assemblies directly affect safety, continuity of service, and system control. Understanding the requirements associated with 27-1942 can help reduce ambiguity in repair, replacement, and documentation work. It may also assist with design review and compliance comparisons when older equipment must be assessed against archived expectations rather than current practice.
