IEEE 487.3-2014

IEEE 487.3-2014 addresses the electrical protection of communication facilities serving electric supply locations through the use of hybrid facilities. This standard is relevant where communication paths must operate alongside power-system environments while maintaining protection from electrical hazards and disturbances. IEEE 487.3-2014 helps define a technical basis for designing and evaluating these facilities so communication support remains dependable in demanding utility settings and related engineering applications.

About IEEE 487.3-2014

This technical document focuses on protection requirements for communication facilities that serve electric supply locations, especially where hybrid facilities are involved. In practice, that means coordinating communication infrastructure with electrical-system conditions that may create exposure to surges, fault currents, grounding concerns, or interference. The standard is useful for engineers who need a clearer reference for safety-oriented design and for comparing system approaches during specification, review, or procurement. It supports more consistent decisions around facility protection and operational reliability.

Where is IEEE 487.3-2014 used?

IEEE 487.3-2014 is typically used in utility communication environments tied to electric supply locations, such as substations or related support facilities where hybrid communication paths are part of the installation. It is relevant to planning, upgrading, and maintaining communications equipment that must coexist with power-distribution infrastructure. The standard may also inform work on grounding, insulation coordination, and protective arrangements for systems that carry both communication and electrical considerations within the same operational setting.

Importance in practice

In practice, this standard helps reduce uncertainty when communication facilities must function safely near electrical supply equipment. It can support more consistent engineering reviews, clearer specification language, and better alignment between design teams, operators, and procurement needs. For compliance and testing, IEEE 487.3-2014 offers a shared reference point for evaluating protective measures and identifying weak points in hybrid facility designs. That consistency can help limit outage risk, safety exposure, and unnecessary redesign during project execution.
