About This Item
IEEE PC37.04b/D14, Apr 2008 is a draft amendment tied to the rating structure for ac high-voltage circuit breakers rated on a symmetrical current basis. It focuses on the description of transient recovery voltage, helping align terminology and technical interpretation with IEC 62271-100. For power and energy applications, this kind of update matters because accurate TRV language supports consistent ratings, testing, and specification reviews for high-voltage switching equipment.
About IEEE PC37.04b/D14, Apr 2008
This technical document serves as an amendment to the IEEE standard for circuit breaker rating structure, with emphasis on how transient recovery voltage is described in the context of symmetrical current ratings. IEEE PC37.04b/D14, Apr 2008 is relevant to engineers who work with breaker performance definitions, rating coordination, and harmonization between IEEE and IEC terminology. It helps clarify the language used when specifying interruption capability and related electrical duties for ac high-voltage circuit breakers.
Where is IEEE PC37.04b/D14, Apr 2008 used?
IEEE PC37.04b/D14, Apr 2008 is typically used in the specification and review of ac high-voltage circuit breakers for utility substations, switchgear projects, and other power-system installations. It is especially relevant where transient recovery voltage details affect breaker selection, rating verification, or test interpretation. In practice, the document supports engineering teams, manufacturers, and procurement specialists working with equipment that must meet defined symmetrical current basis ratings and consistent technical descriptions.
Importance in practice
Clear TRV wording is important because breaker ratings and test obligations depend on precise technical definitions. IEEE PC37.04b/D14, Apr 2008 helps reduce ambiguity in design documentation, compliance checks, and bid comparisons for high-voltage circuit breakers. By harmonizing the description with IEC 62271-100, it can improve consistency across standards-based workflows and lower the risk of misinterpretation during engineering review, factory testing, or project acceptance.
