IEEE C37.20.2b-1994

C37.20.2b-1994 is a technical standard focused on type cubicle switchgear current transformer accuracies, helping define how these devices should perform in power, energy, and industrial applications. It is relevant where current transformers are used inside switchgear assemblies and measurement accuracy affects system evaluation, protection, and accountability. As a superseded document, C37.20.2b-1994 is mainly useful for legacy reference, comparison, and historical compliance review.

What is C37.20.2b-1994?

C37.20.2b-1994 addresses accuracy requirements for current transformers associated with type cubicle switchgear. In practical terms, it helps frame how transformer performance is characterized when installed in enclosed switchgear equipment used for electrical distribution and control. The standard supports engineering consistency by setting expectations around measurement behavior rather than general construction alone. For users reviewing legacy equipment or documentation, C37.20.2b-1994 provides a focused technical reference for accuracy-related requirements.

Where is C37.20.2b-1994 used?

This standard is typically applied in switchgear installations where current transformers support metering, protection, or monitoring functions. It is most relevant to power and energy systems, utility facilities, and industrial electrical distribution equipment that uses cubicle-style switchgear. Engineers, specification writers, and maintenance teams may refer to C37.20.2b-1994 when evaluating transformer accuracy in enclosed assemblies, especially during equipment review, procurement, or legacy system support.

Why is C37.20.2b-1994 important?

C37.20.2b-1994 matters because current transformer accuracy directly affects measurement confidence and protection performance in switchgear applications. Clear accuracy expectations help reduce design uncertainty, support consistent testing, and improve comparison between equipment options. For organizations maintaining older systems, the standard can also aid compliance review and documentation checks. By defining a focused technical baseline, C37.20.2b-1994 helps limit risk in power, energy, and industrial electrical work.
