About This Item
IEEE PC37.04-1999/Cor1_DB2, Apr 2009 is a draft corrigendum to the IEEE Std C37.04-1999 rating structure for AC high-voltage circuit breakers. It addresses corrections to the breaker rating framework used in power and energy applications, helping engineers apply the standard with greater consistency. For teams working on high-voltage switchgear documentation, procurement, or compliance review, this technical document helps clarify how ratings are stated and interpreted.
IEEE PC37.04-1999/Cor1_DB2, Apr 2009 overview
This standard item sits in the IEEE C37 family and is tied to the rating structure for AC high-voltage circuit breakers. As a corrigendum to IEEE Std C37.04-1999, it is intended to correct or refine specific provisions rather than define an entirely new framework. IEEE PC37.04-1999/Cor1_DB2, Apr 2009 is therefore relevant when a project needs accurate reference text for breaker ratings, technical comparison, or specification alignment in utility and industrial power systems.
Typical use cases
This corrigendum is commonly used when preparing or reviewing specifications for AC high-voltage circuit breakers, especially where rating values must match IEEE terminology and structure. It may support equipment selection for substations, transmission networks, and other power system installations that rely on consistent breaker ratings. Engineering teams, standards librarians, and procurement staff can use IEEE PC37.04-1999/Cor1_DB2, Apr 2009 to verify technical references in design packages, bid documents, and compliance records.
Why this standard matters
Accurate rating information is essential for safe and consistent breaker application. By correcting the base 1999 standard, IEEE PC37.04-1999/Cor1_DB2, Apr 2009 helps reduce ambiguity in design review, testing expectations, and equipment documentation. That can support better procurement decisions, clearer manufacturer comparisons, and lower risk of mismatch between specified and installed high-voltage circuit breaker capabilities. In practice, this improves confidence in system coordination and technical compliance.
