IEEE C62.48-1995

C62.48-1995 is a protective devices standard for power, energy, and industry applications, providing technical guidance that supports the selection and application of equipment intended to guard electrical systems against abnormal conditions. As a superseded English-language standard, it remains relevant for understanding earlier requirements and design practices around protection methods, coordination, and performance expectations. For engineers, specifiers, and compliance teams, it helps clarify how protective functions were addressed in utility and industrial power systems.

About C62.48-1995

This standard focuses on protective devices in electrical power and energy contexts, where controlled interruption, isolation, or mitigation of faults is essential to reliable operation. C62.48-1995 is useful for identifying the technical framework associated with protective equipment and the way such devices are expected to support system integrity. In practice, it may be consulted when reviewing specifications, comparing legacy equipment requirements, or interpreting historical engineering documents tied to power-system protection and industrial electrical design.

Where is C62.48-1995 used?

C62.48-1995 is most relevant in utility power networks, industrial distribution systems, and engineering workflows that involve protective relays, interrupters, fuses, or other fault-limiting devices. It can also be useful in maintenance planning, refurbishment projects, and procurement activities where legacy standards still shape equipment selection or documentation. Because the subject is tied to power, energy, and industry applications, the standard is especially helpful when assessing protective-device requirements within electrical infrastructure and operating environments.

Importance in practice

Protective-device standards matter because they influence how systems respond to overloads, short circuits, and other abnormal conditions. C62.48-1995 can help support consistent design review, safer equipment application, and more reliable comparison of technical requirements across projects or legacy specifications. For organizations working with older power equipment, it may reduce ambiguity during testing, compliance assessment, and replacement planning. That makes it valuable for managing risk and maintaining continuity in electrical operations.
