About This Item
IEEE P1268/D4 is an unapproved IEEE draft guide focused on the safe installation of mobile substation equipment, a topic that sits within power, energy, and industry applications. It is a revision of IEEE 1268-1997 and is marked inactive, so it is best understood as a draft technical reference rather than a current enforceable requirement. For teams working with mobile substation setups, it helps define installation practices that may reduce hazards and improve consistency.
What is IEEE P1268/D4?
IEEE P1268/D4 provides draft guidance for planning and carrying out the installation of mobile substation equipment. The document’s main emphasis is safety, with attention to how temporary or relocatable substation assets are positioned, connected, and brought into service. Because it is a draft guide, it is typically used as a technical reference for engineering judgment, project planning, and internal procedures rather than as a finalized standard. The revision history also makes it relevant for comparing older installation practices with later draft recommendations.
Where is IEEE P1268/D4 used?
This draft guide is most relevant in utility and industrial power environments where mobile substations are deployed for temporary service, contingency support, maintenance outages, or emergency restoration. It may be used by engineering, field installation, and commissioning teams responsible for setting up portable substations, associated switchgear, grounding arrangements, and interconnections. Because IEEE P1268/D4 addresses safe installation, it is especially useful during site preparation, equipment placement, and startup planning for energized power systems.
Why is IEEE P1268/D4 important?
IEEE P1268/D4 matters because mobile substation installations can introduce elevated safety and coordination risks if equipment is not installed consistently. A guide like this supports better control over layout, connection practices, and operating precautions, which can help reduce errors during field deployment. It also gives procurement, engineering, and project teams a common technical reference when specifying installation expectations or reviewing contractor work. For organizations managing temporary power assets, that consistency can improve safety and decision-making.
