About This Item
IEEE PC37.90/D15, Jan 2004 is an unapproved draft standard focused on relays and relay systems associated with electric power apparatus. It addresses technical expectations for protection and control equipment used in power applications, where reliable operation and consistent design practices matter. As a draft document, IEEE PC37.90/D15, Jan 2004 is useful for understanding proposed requirements and engineering direction for relay-related systems before finalization.
What is IEEE PC37.90/D15, Jan 2004?
IEEE PC37.90/D15, Jan 2004 is a draft technical standard within the relay and relay system area for electric power apparatus. It is intended to guide how protective relays and related systems are defined, evaluated, and applied in power engineering contexts. The document is especially relevant when comparing draft requirements, reviewing testing expectations, or studying how relay performance may be addressed for control, protection, and coordination functions in electrical equipment and installations.
Where is IEEE PC37.90/D15, Jan 2004 used?
This draft standard is most relevant in utility protection systems, substation control equipment, and other installations that depend on relays for monitoring and operating electric power apparatus. It may also be consulted by engineers working on protection schemes, relay panels, and equipment coordination in generation, transmission, or distribution settings. In practice, IEEE PC37.90/D15, Jan 2004 supports technical review where relay behavior, system interface, and power-sector application requirements need careful attention.
Why is IEEE PC37.90/D15, Jan 2004 important?
IEEE PC37.90/D15, Jan 2004 matters because relay systems must perform predictably in critical power applications, where design choices can affect safety, continuity, and equipment protection. Even as an inactive draft, it can help clarify the intended technical direction for compliance review, procurement checks, and engineering evaluation. It is also useful when teams need a reference point for testing, comparison, or documenting requirements tied to relay performance in electric power apparatus.
