IEEE P1138/D13.3, Feb, 2009

IEEE P1138/D13.3, Feb, 2009 is a draft standard focused on testing and performance for optical ground wire (OPGW) used on electric utility power lines. It addresses how this combined grounding and communications cable is evaluated for service on overhead transmission routes, where electrical grounding and fiber-optic functions must work together reliably. For utilities, engineers, and procurement teams, the document helps define a common basis for performance expectations, test methods, and design review.

What is IEEE P1138/D13.3, Feb, 2009?

This draft document outlines requirements and test considerations for OPGW intended for power line applications. IEEE P1138/D13.3, Feb, 2009 is centered on the technical behavior of the cable as both a grounding conductor and a communications path, so performance evaluation is a key part of its scope. In practical terms, it supports consistency in how materials, construction, and operational characteristics are assessed before installation or procurement.

Where is IEEE P1138/D13.3, Feb, 2009 used?

This standard is most relevant in electric utility transmission systems that use optical ground wire on overhead power lines. It may be used by utility engineers, cable suppliers, test laboratories, and project teams responsible for line design, replacement, or expansion work. The document is also useful where optical communication is carried on the same infrastructure that provides lightning shielding and grounding, especially in long-distance transmission corridors and grid communications applications.

Why is IEEE P1138/D13.3, Feb, 2009 important?

IEEE P1138/D13.3, Feb, 2009 matters because OPGW must perform reliably in a demanding environment while supporting both power-system and communications needs. Clear testing and performance guidance can reduce installation risk, improve procurement comparisons, and support consistent quality control across projects. For utility applications, that means better confidence in mechanical durability, electrical function, and long-term service behavior when the cable is exposed to line loading, weather, and operational stresses.
