IEEE 487-2007

487-2007 is a technical standard for line communication facilities serving electric supply locations, addressing how communications support power and energy operations. In this context, it is relevant to facilities that depend on reliable signaling, monitoring, and coordination across electrical sites. As a superseded document, 487-2007 remains useful for historical reference, legacy design review, and comparison work where older communication requirements still affect engineering decisions or procurement documentation.

Overview of 487-2007

This standard focuses on communication facilities used at electric supply locations, where line communication may be part of operational control, status reporting, or coordination between connected sites. 487-2007 is best understood as a technical reference for the communication side of power-system infrastructure rather than for general-purpose networking. It is typically relevant where electrical service reliability, signal integrity, and compatibility with site-specific equipment are important. The document can help clarify how these facilities were expected to be organized and applied in practice.

Typical use cases

487-2007 may be used when reviewing communication arrangements for substations, utility control points, generation-related facilities, or other electric supply locations. It is relevant to engineers and planners working with line communication equipment, interface points, and operational links that support power-system functions. The standard can also assist during maintenance, replacement planning, or documentation of legacy installations where older communication methods remain in service. In these settings, the focus is often on dependable connection paths and practical interoperability.

Why it matters

Standards like 487-2007 help reduce uncertainty in the design and evaluation of communication facilities tied to electric supply operations. Clear requirements support consistency across sites, improve procurement comparisons, and help teams assess whether existing arrangements meet expected technical practices. For legacy systems, the document can be especially useful when checking compatibility, identifying risk areas, or documenting older configurations. Using a defined standard also supports more predictable testing, maintenance, and long-term operational planning.
