About This Item
PC37.04b/D15, Sept 2008 is a technical standard document for voltage circuit breakers rated on a symmetrical current basis, with an amendment focused on the description of transient recovery voltage for harmonization with IEC 62271-100. It is relevant to power, energy, and industry applications where circuit-breaker ratings and test language must be consistent and clearly defined. As an inactive document, PC37.04b/D15, Sept 2008 is most useful for referencing the specific wording and technical basis used at that time.
PC37.04b/D15, Sept 2008 overview
This document addresses how voltage circuit breakers are identified and described when ratings are expressed on a symmetrical current basis. The amendment refines the way transient recovery voltage is characterized, helping align terminology and technical interpretation with IEC 62271-100. For engineers, specifiers, and procurement teams, PC37.04b/D15, Sept 2008 supports clearer comparison of breaker performance, test conditions, and rating language in electrical power systems. It is especially relevant where precise harmonization matters in equipment documentation.
Typical use cases
PC37.04b/D15, Sept 2008 is typically consulted when preparing or reviewing specifications for medium- and high-voltage circuit breakers, especially in utilities, industrial substations, and switchgear projects. It may be used during rating checks, test planning, and documentation review for transient recovery voltage requirements. The standard is also helpful when comparing legacy IEEE-based terminology with IEC-aligned descriptions, or when interpreting breaker performance data for procurement, compliance, and engineering validation in power system applications.
Why this standard matters
This standard matters because circuit-breaker ratings and test descriptions must be consistent to reduce ambiguity in design, procurement, and compliance work. By clarifying transient recovery voltage terminology, PC37.04b/D15, Sept 2008 helps support more reliable communication between manufacturers, engineers, and buyers. In practice, that can improve specification accuracy, testing consistency, and risk control when selecting or evaluating voltage circuit breakers for critical power applications. It is especially useful when matching technical documents across different standards frameworks.
