About This Item
IEEE PC37.04/D4, Mar 2018 is a draft technical document for ratings and requirements for AC high voltage circuit breakers with rated maximum voltage above 1000 V. It helps define how these breakers are specified, evaluated, and compared in power equipment applications where voltage performance and interruption capability are critical. For engineers, buyers, and compliance teams, IEEE PC37.04/D4, Mar 2018 supports more consistent technical communication around design expectations, testing, and procurement.
About IEEE PC37.04/D4, Mar 2018
This IEEE draft standard addresses the electrical ratings and requirements associated with AC high voltage circuit breakers intended for use above 1000 V. It is relevant to the technical definition of breaker performance, including how equipment is characterized for service conditions and system integration. As a draft standard, IEEE PC37.04/D4, Mar 2018 is especially useful when reviewing specifications, comparing products, or aligning project requirements with established IEEE terminology and rating practices in power engineering.
Where is IEEE PC37.04/D4, Mar 2018 used?
IEEE PC37.04/D4, Mar 2018 is typically used in the planning, specification, and evaluation of AC high voltage circuit breakers for electrical power systems. It is most relevant in substations, utility distribution and transmission equipment, industrial power installations, and other high-voltage applications where interruption performance and rated voltage matter. The document can also support engineering teams working with switchgear, breaker procurement, and system design reviews that depend on clear rating and requirements language.
Importance in practice
In practice, this standard helps reduce ambiguity when selecting and assessing high voltage circuit breakers. Clear ratings and requirements can improve design control, support safer equipment matching, and make testing and acceptance criteria easier to interpret. IEEE PC37.04/D4, Mar 2018 is also useful for procurement teams that need a common technical basis when comparing manufacturers or checking compliance with project specifications. For power applications, that consistency can lower risk and improve reliability.
