This project will provide recommended engineering design practices for special high-voltage protection systems intended to protect wire-line telecommunication facilities serving electric supply locations such as power stations and power line supporting structures.
To review and update existing standard 487-1992.
Revision Standard – Superseded. Workable methods for protecting wire-line communication circuits entering electric supply locations are presented. This document covers: the electric supply location environment; protection apparatus; services types, reliability, service performance objective classifications, and transmission considerations; protection theory and philosophy; protection configurations; installation and inspection; and safety.
