IEEE 487-1992

487-1992 is a superseded standard for line communication facilities serving electric power stations, with a technical focus on communication, networking, and broadcast technologies in power-system environments. It is relevant where dependable line-based communications are needed to support station operations, coordination, and control. For teams reviewing legacy specifications or maintaining older installations, this document helps define the expected technical framework and supports more consistent engineering decisions for station communications.

487-1992 overview

The 487-1992 standard addresses communication facilities intended for use in electric power stations, where reliable signaling and information transfer can be important to operations. Its subtitle points to line communication facilities, which generally suggests communication over dedicated lines or similar transmission paths rather than general-purpose public networks. As a superseded technical document, it is most useful for understanding historical requirements, documenting legacy systems, or comparing older station communication practices against current engineering needs.

Typical use cases

This standard may be used when evaluating line communication arrangements for power station control rooms, substation-adjacent facilities, or utility communication paths that support operational coordination. It is especially relevant to systems that depend on stable, point-to-point communication links for station monitoring, dispatch interaction, or internal engineering communications. Procurement and maintenance teams may also consult 487-1992 when working with legacy communication equipment, cable-based interfaces, or older utility networking practices within power and energy facilities.

Why this standard matters

Even though it is superseded, the document remains valuable for consistency in design review, compliance checks, and legacy asset management. Clear technical requirements for line communication facilities can reduce misinterpretation during refurbishment, replacement, or interoperability planning. For electric power stations, consistent communication performance is closely tied to operational reliability, so having a defined reference helps limit integration risk and supports better documentation of inherited systems. 487-1992 can also assist teams comparing older installations with current practice.
