IEEE C37.23-1987

C37.23-1987 is a technical standard for phase bus applications in power, energy, and industrial systems. It addresses the design and performance considerations that help define how phase bus arrangements are specified and evaluated in electrical installations. For engineers, procurement teams, and compliance reviewers, C37.23-1987 provides a common reference point for comparing solutions and reducing ambiguity when working with bus construction and related requirements.

What is C37.23-1987?

C37.23-1987 is a standards document focused on phase bus requirements within electrical power applications. In practical terms, it supports the specification of bus arrangements used to carry phase conductors in equipment and installations where reliable current transfer and controlled electrical performance matter. The standard is relevant to technical planning, design coordination, and review of materials and construction details. As a superseded standard, it is also useful for understanding legacy designs and historical compliance references tied to C37.23-1987.

Where is C37.23-1987 used?

This standard is typically used in power-system equipment, utility-related installations, and industrial electrical assemblies where phase bus construction is part of the design. It may apply to buswork in substations, switchgear environments, and other high-power distribution settings that require structured phase separation and dependable electrical behavior. C37.23-1987 is especially relevant when working with older specifications, maintenance documentation, or procurement records that reference phase bus requirements in the power and energy sector.

Why is C37.23-1987 important?

C37.23-1987 matters because it helps establish a consistent basis for design review, sourcing, and technical acceptance of phase bus systems. Using a defined standard can support safer layouts, clearer performance expectations, and more reliable comparison between products or legacy installations. It also reduces the risk of misinterpretation in engineering and purchasing documents, where phase bus details can affect fit, function, and compliance. For superseded equipment references, it remains valuable for documentation and historical traceability.
