96 regardless of whether or not the cable tray is being used as an equipment grounding conductor (EGC). A cable tray grounding is best inspected by searching cable tray sections with bonding jumpers (the thick green or copper wires connecting various sections of the tray) and checking them with a device known as a multimeter. The EGC is the most important conductor in an electrical system as its function is electrical safety.

This document provides procedures for installing OPGW fiber optic cables on transmission lines between 35kV and 400kV. OPAC (optical power attached cable) is a type of fiber optic cable that is installed by attaching to a host conductor along overhead power lines. Distributed fiber optic sensing (DFOS) techniques such as Distributed Temperature Sensing (DTS), Distributed Acoustic Sensing (DAS) and Distributed Strain Sensing (DSS) are powerful tools for monitoring of long, linear assets.
