Description / Abstract:
This guide presents an overview of the existing and emerging
temperature monitoring systems related to power cable
installations. It summarizes the features, benefits, and
limitations of both discrete and distributed temperature monitoring
for cable ratings. This guide addresses the various aspects of
userinterface and data communication issues needed to make the
system more effective and more userfriendly.
Purpose
The purpose of this guide is to assist users in applying offline
or real-time temperature monitoring of power cable systems by
addressing the following major issues:
a) Type of cable system installation: existing or new.
b) Circuit length, type of terrain, and backfill along the cable
route that may favor the use of distributed rather than discrete
temperature measurement or vice versa.
c) Advantages/disadvantages of using a real-time monitoring
versus offline monitoring system.
d) System complexity, performance, reliability, and
maintenance.
e) Recommended design, operating criteria, and data
transfer.
f) Influence of adjacent circuits.
